Custom SQL Template

MSSQL supports custom SQL templates for metadata changes. The template is interpreted using python f-strings.

Here are examples of custom SQL queries for metadata changes:

-- Update schema description
IF NOT EXISTS (SELECT 1 
               FROM {database}.sys.extended_properties 
               WHERE name = N'MS_Description' And
               major_id = SCHEMA_ID('{schema}') AND 
               minor_id = 0
     		)
BEGIN
    EXEC {database}.{schema}.sp_addextendedproperty 
     @name = N'MS_Description', 
     @value = N{description}, 
     @level0type = N'SCHEMA', 
     @level0name = N'{schema}'
END
ELSE
BEGIN
    EXEC {database}.{schema}.sp_updateextendedproperty 
     @name = N'MS_Description', 
     @value = N{description}, 
     @level0type = N'SCHEMA', 
     @level0name = N'{schema}'
END;
