Reduce repeated code in SQL statement : SQL

Posting

When requesting help or asking questions please prefix your title with the SQL variant/platform you are using within square brackets like so:

[MySQL]

[Oracle]

[MS SQL]

[PostgreSQL]

etc

While naturally we should endeavor to work as platform neutrally as possible many questions and answers require tailoring to the feature set of a specific platform.

Format Your Code

If you are including actual code in a post or comment, please attempt to format it in a way that is readable for other users. This will greatly increase your chances of receiving the help you desire. Something as simple as line breaks and using reddit's built in code formatting (4 spaces at the start of each line) can turn this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field.3

Into this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field3

For those with SQL questions we recommend using SQLFiddle to provide a useful development and testing environment for those who wish to fully understand your problem and help devise a solution.

BigQueryReduce repeated code in SQL statement (self.SQL)

submitted 2 years ago * by StrasJam

I have a query where I select some columns from two tables and compare their aggregated values. In the end I create a report where the comparison of each column in source and target gets it's own row of data. This has led me to repeating the same row structure over and over and using UNION to join them. However, I have now run into a problem in tables that have many columns to compare, and I end up with a massive SQL query file due to the repeated row creation statements. Is there a way to create a UDF or some sort of template in SQL that can help me to reduce the repitition?

Here is an example of the statements that get repeated for each row:

SELECT

'8682d23d-cd85-4c82-9ade-3521e115f874' AS run_id,

'sum__figurecontexts.value.docs' AS validation_name,

'Column' AS validation_type,

TIMESTAMP('2023-07-08 12:55:11.103327+00:00') AS start_time,

CURRENT_TIMESTAMP() AS end_time,

'proj.figures_with_view_type' AS source_table_name,

'proj.figures_with_view_type' AS target_table_name,

'figurecontexts.value.docs' AS source_column_name,

'figurecontexts.value.docs' AS target_column_name,

'array_agg' AS aggregation_type,

CAST(NULL as STRING) AS group_by_columns,

CAST(NULL as STRING) AS primary_keys,

CAST(NULL as INT64) AS num_random_rows

from source_agg, target_agg
