    <p>I am trying to call a function in Oracle that truncates the table name I pass in. Unfortunately, I keep getting the following error and have no clue as to why.</p> <pre><code>WARNING: Failed to execute: {? = call trunc_table(?)} because: Invalid column type java.sql.SQLException: Invalid column type at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:113) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:147) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:209) at oracle.jdbc.driver.OracleStatement.getInternalType(OracleStatement.java:3462) at oracle.jdbc.driver.OracleCallableStatement.registerOutParameterInternal(OracleCallableStatement.java:126) at oracle.jdbc. </code></pre> <p>I am able to select rows from the table and print to the console. Also, I was able to call the dbms_utility.get_time() function with no problems. </p> <p>Here is the offending code.</p> <pre><code> def storedProcCall = """{? = call trunc_table(?)}""" sql.call(storedProcCall, [Sql.BOOLEAN, 'YFS_ZIP_CODE_LOCATION']) { println it } </code></pre> <p>I expect to get back a true or false to find out if the function was successful</p> <pre><code>create or replace FUNCTION TRUNC_TABLE (table_name IN VARCHAR2) RETURN BOOLEAN IS cid INTEGER; -- Cursor ID. BEGIN cid := DBMS_SQL.OPEN_CURSOR; DBMS_SQL.PARSE(cid, 'TRUNCATE TABLE ' || table_name, dbms_sql.native); DBMS_SQL.CLOSE_CURSOR(cid); RETURN TRUE; EXCEPTION WHEN OTHERS THEN DBMS_SQL.CLOSE_CURSOR(cid); dbms_output.put_line('Error truncating table: '||table_name); dbms_output.put_line(SQLERRM); RETURN FALSE; END TRUNC_TABLE; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
