Whitespace text found data quality checks, SQL examples
This check detects empty texts containing only spaces and other whitespace characters. This check counts whitespace-only texts and raises a data quality issue when their count exceeds a max_count parameter value.
The whitespace text found data quality check has the following variants for each type of data quality checks supported by DQOps.
profile whitespace text found
Check description
Detects texts that contain only spaces and other whitespace characters. It raises a data quality issue when their count exceeds a max_count parameter value.
Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
---|---|---|---|---|---|---|---|---|
profile_whitespace_text_found |
Maximum count of whitespace values | whitespace | profiling | Completeness | whitespace_text_count | max_count |
Command-line examples
Please expand the section below to see the DQOps command-line examples to run or activate the profile whitespace text found data quality check.
Managing profile whitespace text found check from DQOps shell
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_whitespace_text_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_whitespace_text_found --enable-warning
Additional rule parameters are passed using the -Wrule_parameter_name=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_whitespace_text_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_whitespace_text_found --enable-error
Additional rule parameters are passed using the -Erule_parameter_name=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_whitespace_text_found check on all tables and columns on a single data source.
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.
You can also run this check on all tables (and columns) on which the profile_whitespace_text_found check is enabled using patterns to find tables.
YAML configuration
The sample schema_name.table_name.dqotable.yaml file with the check configured is shown below.

daily whitespace text found
Check description
Detects texts that contain only spaces and other whitespace characters. It raises a data quality issue when their count exceeds a 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_whitespace_text_found |
Maximum count of whitespace values | whitespace | monitoring | daily | Completeness | whitespace_text_count | max_count |
Command-line examples
Please expand the section below to see the DQOps command-line examples to run or activate the daily whitespace text found data quality check.
Managing daily whitespace text found check from DQOps shell
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_whitespace_text_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_whitespace_text_found --enable-warning
Additional rule parameters are passed using the -Wrule_parameter_name=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_whitespace_text_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_whitespace_text_found --enable-error
Additional rule parameters are passed using the -Erule_parameter_name=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_whitespace_text_found check on all tables and columns on a single data source.
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.
You can also run this check on all tables (and columns) on which the daily_whitespace_text_found check is enabled using patterns to find tables.
YAML configuration
The sample schema_name.table_name.dqotable.yaml file with the check configured is shown below.

monthly whitespace text found
Check description
Detects texts that contain only spaces and other whitespace characters. It raises a data quality issue when their count exceeds a 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 |
---|---|---|---|---|---|---|---|---|
monthly_whitespace_text_found |
Maximum count of whitespace values | whitespace | monitoring | monthly | Completeness | whitespace_text_count | max_count |
Command-line examples
Please expand the section below to see the DQOps command-line examples to run or activate the monthly whitespace text found data quality check.
Managing monthly whitespace text found check from DQOps shell
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_whitespace_text_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_whitespace_text_found --enable-warning
Additional rule parameters are passed using the -Wrule_parameter_name=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_whitespace_text_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_whitespace_text_found --enable-error
Additional rule parameters are passed using the -Erule_parameter_name=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_whitespace_text_found check on all tables and columns on a single data source.
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.
You can also run this check on all tables (and columns) on which the monthly_whitespace_text_found check is enabled using patterns to find tables.
YAML configuration
The sample schema_name.table_name.dqotable.yaml file with the check configured is shown below.

daily partition whitespace text found
Check description
Detects texts that contain only spaces and other whitespace characters. It raises a data quality issue when their count exceeds a max_count parameter value. Stores a separate data quality check result for each daily partition.
Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
---|---|---|---|---|---|---|---|---|
daily_partition_whitespace_text_found |
Maximum count of whitespace values | whitespace | partitioned | daily | Completeness | whitespace_text_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 whitespace text found data quality check.
Managing daily partition whitespace text found check from DQOps shell
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_whitespace_text_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_whitespace_text_found --enable-warning
Additional rule parameters are passed using the -Wrule_parameter_name=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_whitespace_text_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_whitespace_text_found --enable-error
Additional rule parameters are passed using the -Erule_parameter_name=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_whitespace_text_found check on all tables and columns on a single data source.
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_whitespace_text_found
You can also run this check on all tables (and columns) on which the daily_partition_whitespace_text_found check is enabled using patterns to find tables.
YAML configuration
The sample schema_name.table_name.dqotable.yaml file with the check configured is shown below.

monthly partition whitespace text found
Check description
Detects texts that contain only spaces and other whitespace characters. It raises a data quality issue when their count exceeds a max_count parameter value. Stores a separate data quality check result for each monthly partition.
Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
---|---|---|---|---|---|---|---|---|
monthly_partition_whitespace_text_found |
Maximum count of whitespace values | whitespace | partitioned | monthly | Completeness | whitespace_text_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 whitespace text found data quality check.
Managing monthly partition whitespace text found check from DQOps shell
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_whitespace_text_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_whitespace_text_found --enable-warning
Additional rule parameters are passed using the -Wrule_parameter_name=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_whitespace_text_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_whitespace_text_found --enable-error
Additional rule parameters are passed using the -Erule_parameter_name=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_whitespace_text_found check on all tables and columns on a single data source.
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_whitespace_text_found
You can also run this check on all tables (and columns) on which the monthly_partition_whitespace_text_found check is enabled using patterns to find tables.
YAML configuration
The sample schema_name.table_name.dqotable.yaml file with the check configured is shown below.
