I have a question regarding where bind variables can be used in a dynamic SQL statement in PL/SQL. For example, I know that this is valid: CREATE OR REPLACE FUNCTION get_num_of_employees (p_loc VARCHAR2, p_job VARCHAR2) RETURN NUMBER. IS. v_query_str VARCHAR2(1000); v_num_of_employees NUMBER; BEGIN. v_query_str := 'SELECT COUNT(*) FROM emp_'.
I will create a temporary table cust_criteria. This table will always contains one row, and I will insert my input values into it. So the dynamic sql will be: v_sql := 'select * from customer a,cust_criteria b where a.firstname = b.firstname and a.lastname = b.lastname'; open c_cursor for v_sql;
V$SQL_BIND_CAPTURE displays information on bind variables used by SQL cursors. Each row in the view contains information for one bind variable defined in a cursor. This includes:
V$SQL_BIND_DATA describes, for each distinct bind variable in each cursor owned by the session querying this view: Actual bind data, if the bind variable is user defined. The underlying literal, if the CURSOR_SHARING parameter is set to FORCE and the bind variable is system generated.
1 Νοε 2017 · How can I find out if a SQL used bind variable or not? I know you can check v$sql and get a list of distinct SQLs after translating the constants in the predicates. But if it's using bind variable, shouldn't V$SQL_BIND_CAPTURE have that SQL_ID and also the values really used for the variables?
22 Φεβ 2023 · Tom, I have a query which is executed from the application server (weblogic) for a report module which uses bind variables. he query as shown in v$sql is shown below. select /*+ first_rows(100)*/ col1,col2 from tab where c1=:1 and c2 >=:2 and c3<=:3.
V$SQL lists statistics on shared SQL areas without the GROUP BY clause and contains one row for each child of the original SQL text entered. Statistics displayed in V$SQL are normally updated at the end of query execution. However, for long running queries, they are updated every 5 seconds.
