is there a way to actually query the database in a such a way to search for a particular value in every table across the whole database ?
Something like a file search in Eclipse, it searches accross the whole worspace and project ?
Sorry about that .. its MS SQL 2005
SQL Workbench/J has a built in tool and command to do that.
It's JDBC based and should also work with SQL Server.
You will need to use the LIKE operator, and search through each field separately. i.e.
SELECT * FROM <table name>
WHERE (<field name1> LIKE '%<search value>%') OR
(<field name2> LIKE '%<search value>%') OR
... etc.
This isn't a quick way though.
I think the best way would be to
1) programatically generate the query and run it
2) use a GUI tool for the SQL server you are using which provides this functionality.
In mysql you can use union operator like
(SELECT * from table A where name = 'abc') UNION (SELECT * from
table B where middlename = 'pqr')
and so on
use full text search for efficency

Well, your best bet is to write a procedure to do this. But to give you some pointers you can use the INFORMATION_SCHEMA.Tables to get a list of all the tables in a given database and INFORMATION_SCHEMA.Columns to get a list of all columns. These tables also give you the datatype of columns. So you will need a few loops on these tables to do the magic.
It should be mentioned most RDBMSs nowadays support these schemas.
In phpmyadmin, go to your database, reach the search tab.
Here you will be able to select all of your tables and search through your entire db in one time.

I need to identify a table that is mentioned anywhere in database (in stored proc, views, and, etc.). I tried to find a query online, but couldn't find it. Any help would be great!
I use the free SQL Search plugin for MS Management Studio for things like that: http://www.red-gate.com/products/sql-development/sql-search/
I often use this snippet when I'm looking for dependencies. In this case, you would replace the text with what you're searching (assuming you're on MS SQL Server):
USE [DBNAME]
SELECT OBJECT_NAME(id)
FROM syscomments
WHERE [text] LIKE '%enter_search_here%'
GROUP BY OBJECT_NAME(id)
You can also look for specific object types by adding a check for object property:
WHERE OBJECTPROPERTY(id, 'IsTable') = 1
Here is a LIST of useful object properties!
I'm using a DB2 database and I'm hoping for a query which will iterate over all stored procedures in a single database and print out the source code of each. No fancy formatting or performance requirements.
The reason for this (in case there's a better way of doing it) is I'm trying to track down usages of a particular table in our stored procs, so I want to be able to do a simple text search through all of them.
Also, I've got access to SQuirreL SQL client if anyone knows of a way via that.
Ah, figured it out. For other's reference:
select ROUTINENAME, TEXT from syscat.routines
where definer not in ('SYSIBM') AND ROUTINESCHEMA='databaseName'
I know this is old, but your answer started me on the right track. We are also using DB2, but don't have syscat.routines visible to us. However we do have SYSIBM.SYSROUTINES and that allows similar by doing
SELECT SCHEMA,
NAME,
TEXT
FROM SYSIBM.SYSROUTINES
WHERE SCHEMA = '<SCHEMA>'
and NAME = '<NAME>'
FOR FETCH ONLY WITH UR;
is there a simple way to just output each record in a select statement to write to its own file?
for example, if you have the tsql query in sql server 2005,
select top 10 items, names + ':' + address from book
and you ended up with 10 text files with the individual name and addresses in each file.
is there a way to do this without writing an extensive spWriteStringToFile procedure? I'm hoping there is some kind of output setting or something in the select statement.
thanks in advance
SQL returns the result set first, there's no opportunity in there for writing records to specific files until afterwards.
Being SQL Server 2005, it's possible you could use a SQLCLR (.NET 2.0 code) function in a SQL statement without having to make a separate application.
In SSMS, you can do a results to file, but that wouldnt split each record out into its own file. I pretty sure you cannot do this out of the box, so it sounds like you will be rolling your own solution.
You'd do this in some client, be it Java, VBA or SSIS typically.
I have a storedproc which has multiple select statement.
When it is executed in sql server , it returns multiple tables.
I need a query which will select a particular table from the storedproc e.g. sp_help.
Please help.
If i have a look at this link, it seems that it is not possible.
Astander is right. From the number of tables available in ur SP, it is not possible directly.
However, you can apply some trick to accomplish your work. I am giving an example here. May be you can generate some idea based on this line.
SELECT * FROM sys.Tables where name =
'my_tbl'
As you can make out that I am filtering out the query by a table among all the tables available in my database.
Something of this sort may help you.
Else, if can get the dataset and then from that get the needed datatable from ur frontend code.
We want to search for a string (ie. "Hello World") in all our database that has about 120 tables. We thought about doing a dump like mysql dump but it came out in a weird bak format.
The search should be done in each column for each table. Is this possible with any type of script, or this is harder than it sounds to me?
How to search all columns of all tables in a database for a keyword
No it possible and easy to write a script to do this.
Suggestions:
I think you have to use some cursors and use some of these objects to write your script
sys.databases
INFORMATION_SCHEMA.TABLES or sys.tables
INFORMATION_SCHEMA.COLUMNS or sys.columns
Once you have these things in place, searching Hello World under all columns would be more simple
Is this just for a one-off, or something you want to do regularly?
If it's a one-off, how about using the export data wizard to export the tables out to CSV files (assuming you're using SQL Server, although I'm sure most databases have equivalents).
Once you've done this you can just do a 'Find Files' in explorer to find all occurrences?
It's a bit dirty - but it'll work!
