Row count change data quality checks, SQL examples
This check compares the current table volume (the row count) to the last known row count. It raises a data quality issue when the change in row count (increase or decrease) exceeds a maximum accepted percentage of change.
The row count change data quality check has the following variants for each type of data quality checks supported by DQOps.
profile row count change
Check description
Detects when the volume's (row count) change since the last known row count exceeds the maximum accepted change percentage.
| Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
|---|---|---|---|---|---|---|---|---|
profile_row_count_change |
Maximum relative change in the row count since the last known value | volume | profiling | Consistency | row_count | change_percent |
Command-line examples
Please expand the section below to see the DQOps command-line examples to run or activate the profile row count change data quality check.
Managing profile row count change 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 -ch=profile_row_count_change --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_* -ch=profile_row_count_change --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 -ch=profile_row_count_change --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_* -ch=profile_row_count_change --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_row_count_change check on all tables 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 on which the profile_row_count_change 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.

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 on which the daily_row_count_change 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 row count change
Check description
Detects when the volume (row count) changes since the last known row count from a previous month exceeds the maximum accepted change percentage.
| Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
|---|---|---|---|---|---|---|---|---|
monthly_row_count_change |
Maximum relative change in the row count since the last known value | volume | monitoring | monthly | Consistency | row_count | change_percent |
Command-line examples
Please expand the section below to see the DQOps command-line examples to run or activate the monthly row count change data quality check.
Managing monthly row count change 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 -ch=monthly_row_count_change --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_* -ch=monthly_row_count_change --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 -ch=monthly_row_count_change --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_* -ch=monthly_row_count_change --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_row_count_change check on all tables 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 on which the monthly_row_count_change check is enabled using patterns to find tables.

daily partition row count change
Check description
Detects when the partition's volume (row count) change between the current daily partition and the previous partition exceeds the maximum accepted change percentage.
| Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
|---|---|---|---|---|---|---|---|---|
daily_partition_row_count_change |
Maximum relative change in the row count since the last known value | volume | partitioned | daily | Consistency | row_count | change_percent |
Command-line examples
Please expand the section below to see the DQOps command-line examples to run or activate the daily partition row count change data quality check.
Managing daily partition row count change 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 -ch=daily_partition_row_count_change --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_* -ch=daily_partition_row_count_change --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 -ch=daily_partition_row_count_change --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_* -ch=daily_partition_row_count_change --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_row_count_change check on all tables 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 on which the daily_partition_row_count_change check is enabled using patterns to find tables.

monthly partition row count change
Check description
Detects when the partition's volume (row count) change between the current monthly partition and the previous partition exceeds the maximum accepted change percentage.
| Data quality check name | Friendly name | Category | Check type | Time scale | Quality dimension | Sensor definition | Quality rule | Standard |
|---|---|---|---|---|---|---|---|---|
monthly_partition_row_count_change |
Maximum relative change in the row count since the last known value | volume | partitioned | monthly | Consistency | row_count | change_percent |
Command-line examples
Please expand the section below to see the DQOps command-line examples to run or activate the monthly partition row count change data quality check.
Managing monthly partition row count change 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 -ch=monthly_partition_row_count_change --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_* -ch=monthly_partition_row_count_change --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 -ch=monthly_partition_row_count_change --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_* -ch=monthly_partition_row_count_change --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_row_count_change check on all tables 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 on which the monthly_partition_row_count_change check is enabled using patterns to find tables.
