SQL Query to search schema of all tables

问题

I am working on a SQL Server 2008 Db that has many tables in it (around 200). Many of these tables contain a field by the name "CreatedDate". I am trying to identify all the table schema with this particular field.

Is there a SQL query to do this?

回答1:

I would query the information_schema - this has views that are much more readable than the underlying tables.

SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME LIKE '%create%'

You can also try doing this using one of many third party tools that are available for this.

Queries are great for simple searches but if you need to do more manipulation with data, search for references and such this is where you can do a much better job with these.

Also, these come in very handy when some objects are encrypted and you need to search for

I’m using ApexSQL Search which is free but there are also many more (also free) on the market such as Red Gate or SSMS Tool Pack.

  select object_name(c.object_id) as table_name
    , schema_name(t.schema_id) as schema_name
    from sys.columns c
    join sys.tables t on c.object_id = t.object_id
     where c.name=N'CreatedDate';

It gets a little more complicated if you want alsoother table properties, but you'll refer to the object catalog views like sys.tables, sys.columns etc.

My favorite...

SELECT objParent.name AS parent, obj.name, col.*
FROM sysobjects obj 
    LEFT JOIN syscolumns col
        ON obj.id = col.id
    LEFT JOIN sysobjects objParent
        ON objParent.id = obj.parent_obj
WHERE col.name LIKE '%Comment%'
   OR obj.name LIKE '%Comment%'

Above I'm searching for "Comment".

Drop the percent signs if you want a direct match.

This searches tables, fields and things like primary key names, constraints, views, etc.

And when you want to search in StoredProcs after monkeying with the tables (and need to make the procs match), use the following...

SELECT name
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%Comment%'

Hope that helps, I find these two queries to be extremely useful.

For me I only have read access to run querys so I need to use this function often here is what I use:

SELECT  *
FROM    INFORMATION_SCHEMA.TABLES
where   TABLES.TABLE_NAME like '%your table name here%'

You can replace .TABLES with .COLUMNS then it would look like this:

 SELECT *
 FROM   INFORMATION_SCHEMA.COLUMNS
 WHERE  columns.COLUMN_NAME like '%your column name here%'

回答6:

Use this query :

SELECT 
    t.name AS table_name,
    SCHEMA_NAME(schema_id) AS schema_name,
    c.name AS column_name , *
FROM sys.tables AS t
    INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID 
Where 
    ( c.name LIKE '%' + '<ColumnName>' + '%' )
    AND 
    ( t.type = 'U' ) -- Use This To Prevent Selecting System Tables

回答7:

Same thing but in ANSI way

SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME IN ( SELECT TABLE_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME = 'CreateDate' )

回答8:

You do not need to type SQL Query for this in SQL Server 2008.

In SSMS Object Explorer choose Databases or Tables of the required database (if you need to search in one database), open menu View--> Object Explorer Details (alternatively press F7), type %CreatedDate% in Search textbox, ENTER, enjoy
