Hi,

I have the following query:

$stid = oci_parse($conn, "SELECT fer, distrito, count(fer),COUNT(CASE WHEN PARC_TOT = 'P' THEN 1 END) COL_P,COUNT(CASE WHEN PARC_TOT = 'T' THEN 1 END) COL_T,COUNT(CASE WHEN (CAUSAS LIKE '%RECE%' OR  CAUSAS LIKE '%RECI%') AND PARC_TOT = 'T' THEN 1 END) COL_REC  FROM INR WHERE FECHA_REC BETWEEN TO_DATE('2014-01-01','YYYY-MM-DD') AND TO_DATE('2014-02-01','YYYY-MM-DD') GROUP BY fer, distrito ORDER BY count(fer) DESC");

The distrito is a number, but I have a table that contains that table with the name. The table is like that


distrito   name
1               lert
2               bcs
3               dffg

how i can change this query to use distrito name and not the number?

Hi,

I don't have the create table statements, because the tables are already created and i don't have the code, i only have access to the tables, sorry about that

Learn about SHOW CREATE TABLE queries.  I'm sure there is some analog in Oracle.

If the number in one table is a lookup value in another table that has a value you want, it is a simple table join.

We would need actual table definitions, sample data and expected results for us to write the exact SQL statement you need.

If you are not familiar with joins:

Focus on the INNER JOIN unless you can have values in the one table that don't exist in the other (then it is an OUTER JOIN).
