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!

Something I have always struggled with is finding DML references to tables in SQL server at the company I work. We have our code held in TFS source control and deployed to a shared development environment so I can search using either file searching or t-sql code. The challenge I have is that I can easily find all references to a table name but I can't find a good way to filter further to a particular statement like UPDATE/INSERT/MERGE.
A large challenge in this is that the company I work at has a lot of dynamic SQL so I think the best method will be some form of text searching. The other challenge is that coding is written as each developer sees fit so an UPDATE statement will not be written in any 'standard' way throughout the code base - i.e. the table name could be on the same line as the DML statement or on a separate line.
I have been able to use some basic regular expression searching in Visual Studio to find instances where the keyword is on the same line as the table name but I don't know how to search for it being 'close'.
Has anybody else faced this issue and found a good way to search for this information? What I would love is a tool where you put in a t-sql reserved keyword and an object name and the tool shows you all references.
One way to at least see all the code across Views, SP, Functions, etc is to run this:
--will show you all source code from procs, views, functions etc
select *
from syscomments
--or better to join it on sysobjects and display only view source code for example
select o.id,o.name,c.text
from syscomments c
inner join sysobjects o on o.id = c.id
where o.[Type] = 'V'
I found once I have all of this, I can then do easy searching in Excel or via Notepad++.
I hope that helped.
I don't know much about the MS world, but now it happens to be that I have to use SQL Server Management Studio 2008.
My problem: I have a column in a table, and I need to see all the stored procedures that may be acting on it.
I tried right-clicking and going 'View Dependencies' but that doesn't seem to be returning everything that it should be.
Questions like this one: SQL Server Dependencies have answers that offer 3 types of solutions
Paid third party tools.
Writing your own scripts.
Exporting everything into text files and grepping them.
WTF? Am I missing something obvious? Is that actually how things work? I would imagine that this is a very common use case: you want to alter table and you want to make sure you won't break anything. Or if say you're looking at a new project with a DB for the first time and you want to see how certain columns get populated with stored procedures. Is there actually no quick and easy built-in workflow to do this?
If you need to find database objects (e.g. tables, columns, triggers) by name - have a look at the FREE Red-Gate tool called SQL Search which does this - it searches your entire database for any kind of string(s).
It's a great must-have tool for any DBA or database developer - did I already mention it's absolutely FREE to use for any kind of use??
Use this query:
SELECT ROUTINE_NAME, ROUTINE_DEFINITION
FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_DEFINITION LIKE '%YOUR COLUMN %'
AND ROUTINE_TYPE='PROCEDURE'
I have spent a good amount of time trying to find a way to identify column level dependencies in a quick way without having to search text or use third party applications. The other challenge is finding dependencies across multiple databases where table names may repeat, which will cause false positives when searching SP text.
As of SQL 2008, there is a function that returns dependencies across databases on a field level.
The code below works with a few exceptions:
It will fail if there are stored procedures with invalid references on tables/fields that have been deleted (Incidently I found this to be useful to find SPs that had been accidentally broken by table modifications).
It doesn't find all dependencies in cases where the SP is using temp tables in unusual ways.
In some cases I found that it was returning false positives for complex stored procedures.
MSDN Documentation
This code should be run from within the database where the SP is in order to be able to cross to other database dependencies.
SELECT
--SP, View, or Function
ReferencingName = o.name,
ReferencingType = o.type_desc,
--Referenced Field
ref.referenced_database_name, --will be null if the DB is not explicitly called out
ref.referenced_schema_name, --will be null or blank if the DB is not explicitly called out
ref.referenced_entity_name,
ref.referenced_minor_name
FROM sys.objects AS o
cross apply sys.dm_sql_referenced_entities('dbo.' + o.name, 'Object') ref
where o.type in ('FN','IF','V','P','TF')
I wonder why you cannot see the dependencies via the 'View Dependencies' dialog because it works perfectly fine for me. Nevertheless you can query the 'sys.sql_expression_dependencies' system view and obtain the dependency information that you want.
Example
SELECT OBJECT_NAME(referencing_id),OBJECT_NAME(referenced_id)
FROM sys.sql_expression_dependencies
WHERE referenced_id = OBJECT_ID('XXX')
You can of course project other information that you might need.
List of All Dependent Objects in single query.
select distinct A.name from sys.procedures A inner join sys.sql_dependencies B
on A.object_id = B.object_id;
OR
select distinct A.name from sys.objects A inner join sys.sql_dependencies B
on A.object_id = B.object_id where A.type_desc = 'mentioned your Object Type';
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
http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html
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 want to search for specific text in all procedures/functions etc. in all databases. I managed to create the required query from this answer but it looks like OBJECT_DEFINITION(OBJECT_ID(SPECIFIC_NAME)) returns NULL for all DBs except the current one.
sp_msforeachdb 'SELECT ''?'' AS DB, SPECIFIC_NAME, OBJECT_DEFINITION(OBJECT_ID(SPECIFIC_NAME)) FROM [?].INFORMATION_SCHEMA.ROUTINES'
You absolutely need Red-Gate's SQL Search tool - it's FREE, and absolutely great and perfectly suited for this need.
The problem is OBJECT_ID cannot be used that way. It only works on the current database. Try returning ROUTINE_DEFINITION directly from INFORMATION_SCHEMA.ROUTINES. This does have a limit of 4000 characters. I'll try to find my other answer on SO which gives my workaround using the MS metadata views.
Have a look at this:
Can you search SQL Server 2005 Stored Procedure content?
try this:
select * from syscomments where [text] like '%yourKeyword%'
I need to write some sql that will allow me to query all objects in our Oracle database. Unfortunately the tools we are allowed to use don't have this built in.
Basically, I need to search all tables, procedures, triggers, views, everything.
I know how to search for object names. But I need to search for the contents of the object.
i.e. SELECT * FROM DBA_OBJECTS WHERE object_name = '%search string%';
Thanks,
Glenn
I'm not sure I quite understand the question but if you want to search objects on the database for a particular search string try:
SELECT owner, name, type, line, text
FROM dba_source
WHERE instr(UPPER(text), UPPER(:srch_str)) > 0;
From there if you need any more info you can just look up the object / line number.
For views you can use:
SELECT *
FROM dba_views
WHERE instr(UPPER(text_vc), UPPER(:srch_str)) > 0
i'm not sure if i understand you, but to query the source code of your triggers, procedures, package and functions you can try with the "user_source" table.
select * from user_source
I would use DBA_SOURCE (if you have access to it) because if the object you require is not owned by the schema under which you are logged in you will not see it.
If you need to know the functions and Procs inside the packages try something like this:
select * from all_source
where type = 'PACKAGE'
and (upper(text) like '%FUNCTION%' or upper(text) like '%PROCEDURE%')
and owner != 'SYS';
The last line prevents all the sys stuff (DBMS_ et al) from being returned. This will work in user_source if you just want your own schema stuff.
i reached this question while trying to find all procedures which use a certain table
Oracle SQL Developer offers this capability, as pointed out in this article : https://www.thatjeffsmith.com/archive/2012/09/search-and-browse-database-objects-with-oracle-sql-developer/
From the View menu, choose Find DB Object. Choose a DB connection. Enter the name of the table. At Object Types, keep only functions, procedures and packages. At Code section, check All source lines.
ALL_SOURCE describes the text source of the stored objects accessible to the current user.
Here is one of the solution
select * from ALL_SOURCE where text like '%some string%';
In Oracle 11g, if you want to search any text in whole database or procedure below mentioned query can be used:
select * from user_source WHERE UPPER(text) LIKE '%YOUR SAGE%'
