Find for SQL Objects, Entities or Text

,

This Stored Procedure will help you to find database objects such as tables, stored procedures, views or function by its name. You can find for table(s) having a specific column.

While working on project we often do impact analysis. Most of the changes in application directly affect the database. Hence we need to figure out the tables having a particular column and the stored procedures using the column in the quries written inside them. I used to do the same task in my project work.

To minimize the time effort involved in such tasks I though to have a basic tool which will perform a quick search for me and return list of almost all objects (tables, stored procedures, views....) mathcing the specified condition.

So I created a stored procedure which will do the job for me.

Lets have a look at the code one by one.

Stored Procedure Name: uspFindObjects

Parameters of Stored Procedure.

1. @ObjectType

Type of object to search. You search for a table or stored procedure by its name. Following @ObjectType can be passed to stored procedure.

- U = Table

- P = Stored Procedure

- V = View

- FN = Function

- * = Find All (Tables, SP, Views, Functions)

2. @SearchText

Text to search

3. @SearchType

Type of data to search

- C = Search for a column

- T = Search for a text

4. @OrderBy

This specifies the field by which order the result should be returned. This parameter is optinal. By defult result is return in order of object name (@OrderBy='N'). Anything other by 'N' is Object type.

Lets have an example to understand it better.

DataBase: MyTestDatabase

We have a table Client_Master with following structure.

Table Name : Client_Master

Column Name Data Type
Client_ID NUMERIC (10)
Client_Name VARCHAR (100)

Then lets have a stored procedure spClientList as

CREATE STORED PROCEDURE spClientList AS

( Select Client_ID,Client_Name FROM Client_Master)

Now we can perform search as displayed below:

1. Seach for the table named Client_Master in list of tables

EXEC uspFindObjects 'U','Client_Master','N'

2. Seach for the SP named spClientList in entire database

EXEC uspFindObjects '*','spClientList','N'

3. Seach for the column Client_ID in tables

EXEC uspFindObjects 'U','Client_ID','C'

4. Seach for the column Client_ID in stored procedures

EXEC uspFindObjects 'P','Client_ID','T'

5. Seach for the column Client_ID in all SP/Views/Functions in entire database

EXEC uspFindObjects '*','Client_ID','T'

This way you can search for the specific objects in a database.

I have provided the comments in stored procedure code to understand it better. Hence I will not explain rest fo the code here again.

Hope the code helps you and provides better understanding of how to look for DB objects in system tables.

Example 1:    To search table with a name:
        
        EXEC uspFindObjects 'U','Client_Master','N'

Example 2:     To search table/stored procedure/views with specific name
        
        EXEC uspFindObjects '*','Client_Master','N'

Example 3:    To seach tables having specific columns

        EXEC uspFindObjects 'U','Client_ID','C'

Example 4:    To search text inside any Stored Procedure/View/Function

        EXEC uspFindObjects '*','City_Name','T'
