First, create a table macro that performs this for each table: CREATE OR REPLACE MACRO table_checksum(table_name) AS TABLE SELECT bit_xor(value) AS table_checksum FROM ( UNPIVOT ( SELECT bit_xor(md5_number(COLUMNS(*)::VARCHAR)) FROM query_table(table_name) ) ON columns(*) ); You need to call this m…
