Text surrounded by whitespace found data quality checks, SQL examples

This check detects text values that contain additional whitespace characters before or after the text. This check counts text values surrounded by whitespace characters (on any side) and raises a data quality issue when their count exceeds a max_count parameter value. Whitespace-surrounded texts should be trimmed before loading to another table.

---

The text surrounded by whitespace found data quality check has the following variants for each type of data quality checks supported by DQOps.

profile text surrounded by whitespace found

Check description

Detects text values that are surrounded by whitespace characters on any side. This check counts whitespace-surrounded texts and raises a data quality issue when their count exceeds the max_count parameter value.

Data quality check name	Friendly name	Category	Check type	Time scale	Quality dimension	Sensor definition	Quality rule	Standard
profile_text_surrounded_by_whitespace_found	Maximum count of text surrounded by whitespace characters	whitespace	profiling		Consistency	text_surrounded_by_whitespace_count	max_count

Command-line examples

Please expand the section below to see the DQOps command-line examples to run or activate the profile text surrounded by whitespace found data quality check.

Managing profile text surrounded by whitespace found check from DQOps shell

Activate the check with a warning ruleActivate the check with an error ruleRun all configured checks

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the warning rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name -col=column_name -ch=profile_text_surrounded_by_whitespace_found --enable-warning

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=profile_text_surrounded_by_whitespace_found --enable-warning

Additional rule parameters are passed using the -Wrule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=profile_text_surrounded_by_whitespace_found --enable-warning
                    -Wmax_count=value

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the error rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name -col=column_name -ch=profile_text_surrounded_by_whitespace_found --enable-error

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=profile_text_surrounded_by_whitespace_found --enable-error

Additional rule parameters are passed using the -Erule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=profile_text_surrounded_by_whitespace_found --enable-error
                    -Emax_count=value

Run this data quality check using the check run CLI command by providing the check name and all other targeting filters. The following example shows how to run the profile_text_surrounded_by_whitespace_found check on all tables and columns on a single data source.

dqo> check run -c=data_source_name -ch=profile_text_surrounded_by_whitespace_found

It is also possible to run this check on a specific connection and table. In order to do this, use the connection name and the full table name parameters.

dqo> check run -c=connection_name -t=schema_name.table_name -ch=profile_text_surrounded_by_whitespace_found

You can also run this check on all tables (and columns) on which the profile_text_surrounded_by_whitespace_found check is enabled using patterns to find tables.

dqo> check run -c=connection_name -t=schema_prefix*.fact_* -col=column_name_* -ch=profile_text_surrounded_by_whitespace_found

daily text surrounded by whitespace found

Check description

Detects text values that are surrounded by whitespace characters on any side. This check counts whitespace-surrounded texts and raises a data quality issue when their count exceeds the max_count parameter value. Stores the most recent captured value for each day when the data quality check was evaluated.

Data quality check name	Friendly name	Category	Check type	Time scale	Quality dimension	Sensor definition	Quality rule	Standard
daily_text_surrounded_by_whitespace_found	Maximum count of text surrounded by whitespace characters	whitespace	monitoring	daily	Consistency	text_surrounded_by_whitespace_count	max_count

Command-line examples

Please expand the section below to see the DQOps command-line examples to run or activate the daily text surrounded by whitespace found data quality check.

Managing daily text surrounded by whitespace found check from DQOps shell

Activate the check with a warning ruleActivate the check with an error ruleRun all configured checks

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the warning rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name -col=column_name -ch=daily_text_surrounded_by_whitespace_found --enable-warning

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=daily_text_surrounded_by_whitespace_found --enable-warning

Additional rule parameters are passed using the -Wrule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=daily_text_surrounded_by_whitespace_found --enable-warning
                    -Wmax_count=value

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the error rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name -col=column_name -ch=daily_text_surrounded_by_whitespace_found --enable-error

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=daily_text_surrounded_by_whitespace_found --enable-error

Additional rule parameters are passed using the -Erule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=daily_text_surrounded_by_whitespace_found --enable-error
                    -Emax_count=value

Run this data quality check using the check run CLI command by providing the check name and all other targeting filters. The following example shows how to run the daily_text_surrounded_by_whitespace_found check on all tables and columns on a single data source.

dqo> check run -c=data_source_name -ch=daily_text_surrounded_by_whitespace_found

It is also possible to run this check on a specific connection and table. In order to do this, use the connection name and the full table name parameters.

dqo> check run -c=connection_name -t=schema_name.table_name -ch=daily_text_surrounded_by_whitespace_found

You can also run this check on all tables (and columns) on which the daily_text_surrounded_by_whitespace_found check is enabled using patterns to find tables.

dqo> check run -c=connection_name -t=schema_prefix*.fact_* -col=column_name_* -ch=daily_text_surrounded_by_whitespace_found

YAML configuration

The sample schema_name.table_name.dqotable.yaml file with the check configured is shown below.

monthly text surrounded by whitespace found

Check description

Detects text values that are surrounded by whitespace characters on any side. This check counts whitespace-surrounded texts and raises a data quality issue when their count exceeds the max_count parameter value. Stores the most recent captured value for each month when the data quality check was evaluated.

Data quality check name	Friendly name	Category	Check type	Time scale	Quality dimension	Sensor definition	Quality rule	Standard
monthly_text_surrounded_by_whitespace_found	Maximum count of text surrounded by whitespace characters	whitespace	monitoring	monthly	Consistency	text_surrounded_by_whitespace_count	max_count

Command-line examples

Please expand the section below to see the DQOps command-line examples to run or activate the monthly text surrounded by whitespace found data quality check.

Managing monthly text surrounded by whitespace found check from DQOps shell

Activate the check with a warning ruleActivate the check with an error ruleRun all configured checks

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the warning rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name -col=column_name -ch=monthly_text_surrounded_by_whitespace_found --enable-warning

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=monthly_text_surrounded_by_whitespace_found --enable-warning

Additional rule parameters are passed using the -Wrule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=monthly_text_surrounded_by_whitespace_found --enable-warning
                    -Wmax_count=value

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the error rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name -col=column_name -ch=monthly_text_surrounded_by_whitespace_found --enable-error

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=monthly_text_surrounded_by_whitespace_found --enable-error

Additional rule parameters are passed using the -Erule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=monthly_text_surrounded_by_whitespace_found --enable-error
                    -Emax_count=value

Run this data quality check using the check run CLI command by providing the check name and all other targeting filters. The following example shows how to run the monthly_text_surrounded_by_whitespace_found check on all tables and columns on a single data source.

dqo> check run -c=data_source_name -ch=monthly_text_surrounded_by_whitespace_found

It is also possible to run this check on a specific connection and table. In order to do this, use the connection name and the full table name parameters.

dqo> check run -c=connection_name -t=schema_name.table_name -ch=monthly_text_surrounded_by_whitespace_found

You can also run this check on all tables (and columns) on which the monthly_text_surrounded_by_whitespace_found check is enabled using patterns to find tables.

dqo> check run -c=connection_name -t=schema_prefix*.fact_* -col=column_name_* -ch=monthly_text_surrounded_by_whitespace_found

daily partition text surrounded by whitespace found

Check description

Detects text values that are surrounded by whitespace characters on any side. This check counts whitespace-surrounded texts and raises a data quality issue when their count exceeds the max_count parameter value. Analyzes every daily partition and creates a separate data quality check result with the time period value that identifies the daily partition.

Data quality check name	Friendly name	Category	Check type	Time scale	Quality dimension	Sensor definition	Quality rule	Standard
daily_partition_text_surrounded_by_whitespace_found	Maximum count of text surrounded by whitespace characters	whitespace	partitioned	daily	Consistency	text_surrounded_by_whitespace_count	max_count

Command-line examples

Please expand the section below to see the DQOps command-line examples to run or activate the daily partition text surrounded by whitespace found data quality check.

Managing daily partition text surrounded by whitespace found check from DQOps shell

Activate the check with a warning ruleActivate the check with an error ruleRun all configured checks

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the warning rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name -col=column_name -ch=daily_partition_text_surrounded_by_whitespace_found --enable-warning

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=daily_partition_text_surrounded_by_whitespace_found --enable-warning

Additional rule parameters are passed using the -Wrule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=daily_partition_text_surrounded_by_whitespace_found --enable-warning
                    -Wmax_count=value

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the error rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name -col=column_name -ch=daily_partition_text_surrounded_by_whitespace_found --enable-error

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=daily_partition_text_surrounded_by_whitespace_found --enable-error

Additional rule parameters are passed using the -Erule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=daily_partition_text_surrounded_by_whitespace_found --enable-error
                    -Emax_count=value

Run this data quality check using the check run CLI command by providing the check name and all other targeting filters. The following example shows how to run the daily_partition_text_surrounded_by_whitespace_found check on all tables and columns on a single data source.

dqo> check run -c=data_source_name -ch=daily_partition_text_surrounded_by_whitespace_found

It is also possible to run this check on a specific connection and table. In order to do this, use the connection name and the full table name parameters.

dqo> check run -c=connection_name -t=schema_name.table_name -ch=daily_partition_text_surrounded_by_whitespace_found

You can also run this check on all tables (and columns) on which the daily_partition_text_surrounded_by_whitespace_found check is enabled using patterns to find tables.

dqo> check run -c=connection_name -t=schema_prefix*.fact_* -col=column_name_* -ch=daily_partition_text_surrounded_by_whitespace_found

monthly partition text surrounded by whitespace found

Check description

Detects text values that are surrounded by whitespace characters on any side. This check counts whitespace-surrounded texts and raises a data quality issue when their count exceeds the max_count parameter value. Analyzes every monthly partition and creates a separate data quality check result with the time period value that identifies the monthly partition.

Data quality check name	Friendly name	Category	Check type	Time scale	Quality dimension	Sensor definition	Quality rule	Standard
monthly_partition_text_surrounded_by_whitespace_found	Maximum count of text surrounded by whitespace characters	whitespace	partitioned	monthly	Consistency	text_surrounded_by_whitespace_count	max_count

Command-line examples

Please expand the section below to see the DQOps command-line examples to run or activate the monthly partition text surrounded by whitespace found data quality check.

Managing monthly partition text surrounded by whitespace found check from DQOps shell

Activate the check with a warning ruleActivate the check with an error ruleRun all configured checks

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the warning rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name -col=column_name -ch=monthly_partition_text_surrounded_by_whitespace_found --enable-warning

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=monthly_partition_text_surrounded_by_whitespace_found --enable-warning

Additional rule parameters are passed using the -Wrule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=monthly_partition_text_surrounded_by_whitespace_found --enable-warning
                    -Wmax_count=value

Activate this data quality using the check activate CLI command, providing the connection name, table name, check name, and all other filters. Activates the error rule with the default parameters.

dqo> check activate -c=connection_name -t=schema_name.table_name -col=column_name -ch=monthly_partition_text_surrounded_by_whitespace_found --enable-error

You can also use patterns to activate the check on all matching tables and columns.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=monthly_partition_text_surrounded_by_whitespace_found --enable-error

Additional rule parameters are passed using the -Erule_parameter_name=value.

dqo> check activate -c=connection_name -t=schema_prefix*.fact_* -col=column_name -ch=monthly_partition_text_surrounded_by_whitespace_found --enable-error
                    -Emax_count=value

Run this data quality check using the check run CLI command by providing the check name and all other targeting filters. The following example shows how to run the monthly_partition_text_surrounded_by_whitespace_found check on all tables and columns on a single data source.

dqo> check run -c=data_source_name -ch=monthly_partition_text_surrounded_by_whitespace_found

It is also possible to run this check on a specific connection and table. In order to do this, use the connection name and the full table name parameters.

dqo> check run -c=connection_name -t=schema_name.table_name -ch=monthly_partition_text_surrounded_by_whitespace_found

You can also run this check on all tables (and columns) on which the monthly_partition_text_surrounded_by_whitespace_found check is enabled using patterns to find tables.

dqo> check run -c=connection_name -t=schema_prefix*.fact_* -col=column_name_* -ch=monthly_partition_text_surrounded_by_whitespace_found
