Suggest edits

The BIND_VARIABLE procedure associates a value with an IN or IN OUT bind variable in a SQL command.

BIND_VARIABLE(<c> NUMBER, <name> VARCHAR2,
  <value> { BLOB | CLOB | FLOAT | INTEGER | NUMBER | ROWID | TIMESTAMP | VARCHAR2 }
  [, <out_value_size> NUMBER ])

Parameters

c

Cursor ID of the cursor for the SQL command with bind variables.

name

Name of the bind variable in the SQL command.

value

Value to be assigned.

out_value_size

If name is an IN OUT variable, defines the maximum length of the output value. If not specified, the length of value is assumed.

Examples

The following anonymous block uses bind variables to insert a row into the emp table.

DECLARE
    curid           NUMBER;
    v_sql           VARCHAR2(150) := 'INSERT INTO emp VALUES ' ||
                        '(:p_empno, :p_ename, :p_job, :p_mgr, ' ||
                        ':p_hiredate, :p_sal, :p_comm, :p_deptno)';
    v_empno         emp.empno%TYPE;
    v_ename         emp.ename%TYPE;
    v_job           emp.job%TYPE;
    v_mgr           emp.mgr%TYPE;
    v_hiredate      emp.hiredate%TYPE;
    v_sal           emp.sal%TYPE;
    v_comm          emp.comm%TYPE;
    v_deptno        emp.deptno%TYPE;
    v_status        INTEGER;
