When encountering the error 2200G: Most Specific Type Mismatch
in a PostgreSQL database, perform the following actions:
EXPLAIN
command with the problematic query to get more insights into how PostgreSQL is executing the query and where it might be failing due to type mismatches. For example:EXPLAIN SELECT * FROM your_table WHERE your_column = 'your_value';
\d table_name;
command in the psql tool to ensure that the data types match the expected values in the query.integer
and your query provides a string, you might need to change it to:SELECT * FROM your_table WHERE your_column = CAST('your_value' AS INTEGER);
SELECT typname, typtype, typcategory FROM pg_type WHERE typname = 'your_type_name';
Replace placeholders like your_table
, your_column
, your_value
, and your_type_name
with the actual names relevant to your situation.
