如何在Java中调用Oracle CURSOR返回过程

Question

I have this Store Procedure being called in PHP, How can I do this in JDBC ?

$searchText = $_POST [ 'searchText1' ];
$sql = 'BEGIN :rc := pa_internal_admin.fn_search_level_1 ( :searchText ); END;';
oci_bind_by_name( $stmt, ":searchText", $searchText, 20 );

This is how I'm calling it

String dbCall = "{call pa_internal_admin.fn_search_level_1(?,?)}";
proc = dbConn.connection().prepareCall( dbCall );
proc.setString(1, searchText);
proc.registerOutParameter(2, OracleTypes.CURSOR);

but getting this;

SQLException caught: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'FN_SEARCH_LEVEL_1' ORA-06550: line 1, column 7: PL/SQL: Statement ignored

Need some help Thanks

Much the same way as PHP:

String dbCall = "{ ? = call pa_internal_admin.fn_search_level_1(?) }";
proc = dbConn.connection().prepareCall( dbCall );
proc.registerOutParameter(1, OracleTypes.CURSOR);
proc.setString(2, searchText);

Or if you prefer, to be even more similar:

String dbCall = "BEGIN ? := pa_internal_admin.fn_search_level_1(?); END;";

You tried to call it as a procedure with two parameters, rather than a function with one; you can't arbitrarily change that in your call.

You can get the cursor back with:

OracleResultSet rSet = (OracleResultSet) proc.getCursor(1);

... and then treat it like any other result set.
