Hi, Can anyone help me to find out a way to check the relationship between tables in mainframes. Suppose i have a table "x" with a column name "x_id".
I want to check if any other table have the same column or any kind of relationship exists between these 2. (assuming table qualifiers are same, ie
abc.X, abc.Y, abc.Z etc where X,Y,Z are the table names. i am using DB2) |

SELECT SUBSTR(TBNAME,1,18) AS TABLE FROM SYSIBM.SYSCOLUMNS
WHERE NAME = 'X_ID'
ORDER BY TABLE |

| If your shop has DB2 admin tools you can check for relationship among tables |

Hi, You can also try this query which is similar to the above:
SELECT * FROM SYSIBM.SYSCOLUMNS WHERE
NAME = 'XXXXX' AND TBCREATOR = 'DB2PROD' AND TBNAME LIKE 'YYYY%'
Here NAME is the COLUMN Name
and TBCREATOR is the HIGH Level Qualifier of the table
and TBNAME is the Table Name |

satyapn9,
welcome, you are todays' recipient of dbz's 'dumb-ass post of the day' award.
1. why select all columns, in this case 47 (db2 v10) when you really only want one? the table name?
2. why have WHERE clauses that look for specific table names,
when the only thing you know is the column name?
3. why did you not bother to read the request from the TS
and provide a solution?
For wasting forum space
and
revealing that you really have little to offer,
you are hereby awarded the DUMB-ASS POST OF THE DAY award |
