Column1 Column2 Column3 Column4 Column5
India

Lonon
Germany
Japan
Table3

upto 50 tables are there. I want to retrieve the table names out of 50 which contains 'Germany' as a column value.
Write a single SQL query. There is no key columns in all the tables.
Hope I am clear.
Thanks in advance |

| Dick, can I vote for the answer? Since it doesn't meet the stated requirements, it can't really be considered an answer to the question. Although the question is lame, at least the person is wanting help. |

you are right, Robert.
If I had edit authority on this board I would amend/delete my post. Done
as far as an answer to the OP's question, I don't know how to extract the table name and validate a table column's value for 50 tables in one SQL.
| Code: |
Select 'table name one'
from table-name-one
where column = 'Germany'
UNION
Select 'table name two'
from table-name-two
where column = 'Germany'
...
UNION
Select 'table name 50'
from table-name-50
where column = 'Germany'
|
maybe someone else can provide an answer.
I apologize to ramanatcs and Abhishek. My previous post was needlessly rude and did not contribute to the thread. |

Hello,

Why? Probably because "I want. . .". Maybe it is some homework assignment.
Given the complete lack of specification of what is really needed (it appears to be a list of every table that has the word "Germany" anywhere in the table?), one way might be to unload the tables and scan the unloaded output for the word "Germany". |
