Text not matching regex found data quality checks, SQL examples
This check validates text values using a pattern defined as a regular expression. It counts the number of invalid values and raises a data quality issue when the number exceeds a threshold.
The text not matching regex found data quality check has the following variants for each type of data quality checks supported by DQOps.
profile text not matching regex found
Check description
Verifies that the number of text values not matching the custom regular expression pattern does not exceed the maximum accepted count.
Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
---|---|---|---|---|---|---|---|---|
profile_text_not_matching_regex_found |
Maximum count of rows containing texts values not matching regex | patterns | profiling | Validity | text_not_matching_regex_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 not matching regex found data quality check.
Managing profile text not matching regex 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_text_not_matching_regex_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_not_matching_regex_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_text_not_matching_regex_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_not_matching_regex_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_text_not_matching_regex_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=profile_text_not_matching_regex_found
You can also run this check on all tables (and columns) on which the profile_text_not_matching_regex_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 text not matching regex found
Check description
Verifies that the number of text values not matching the custom regular expression pattern does not exceed the maximum accepted count.
Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
---|---|---|---|---|---|---|---|---|
daily_text_not_matching_regex_found |
Maximum count of rows containing texts values not matching regex | patterns | monitoring | daily | Validity | text_not_matching_regex_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 not matching regex found data quality check.
Managing daily text not matching regex 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_text_not_matching_regex_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_not_matching_regex_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_text_not_matching_regex_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_not_matching_regex_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_text_not_matching_regex_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_text_not_matching_regex_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 text not matching regex found
Check description
Verifies that the number of text values not matching the custom regular expression pattern does not exceed the maximum accepted count.
Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
---|---|---|---|---|---|---|---|---|
monthly_text_not_matching_regex_found |
Maximum count of rows containing texts values not matching regex | patterns | monitoring | monthly | Validity | text_not_matching_regex_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 not matching regex found data quality check.
Managing monthly text not matching regex 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_text_not_matching_regex_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_not_matching_regex_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_text_not_matching_regex_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_not_matching_regex_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_text_not_matching_regex_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_text_not_matching_regex_found
You can also run this check on all tables (and columns) on which the monthly_text_not_matching_regex_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 text not matching regex found
Check description
Verifies that the number of text values not matching the custom regular expression pattern does not exceed the maximum accepted count.
Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
---|---|---|---|---|---|---|---|---|
daily_partition_text_not_matching_regex_found |
Maximum count of rows containing texts values not matching regex | patterns | partitioned | daily | Validity | text_not_matching_regex_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 not matching regex found data quality check.
Managing daily partition text not matching regex 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_text_not_matching_regex_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_not_matching_regex_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_text_not_matching_regex_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_not_matching_regex_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_text_not_matching_regex_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_text_not_matching_regex_found
You can also run this check on all tables (and columns) on which the daily_partition_text_not_matching_regex_found check is enabled using patterns to find tables.

monthly partition text not matching regex found
Check description
Verifies that the number of text values not matching the custom regular expression pattern does not exceed the maximum accepted count.
Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
---|---|---|---|---|---|---|---|---|
monthly_partition_text_not_matching_regex_found |
Maximum count of rows containing texts values not matching regex | patterns | partitioned | monthly | Validity | text_not_matching_regex_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 not matching regex found data quality check.
Managing monthly partition text not matching regex 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_text_not_matching_regex_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_not_matching_regex_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_text_not_matching_regex_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_not_matching_regex_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_text_not_matching_regex_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_text_not_matching_regex_found
You can also run this check on all tables (and columns) on which the monthly_partition_text_not_matching_regex_found check is enabled using patterns to find tables.
