How to Find a Stored Procedure in all the Databases?

When working with MS SQL Server sometimes you need to find a stored procedure in the databases and all that you know is the name of the stored procedure that your teammate told you that he had used but couldn’t remember in which database it was. All the information about the stored procedures created is saved in the master database. So, if you have access to master database that you probably have then you can run the following query to get information about the stored procedure.

select * 
from 
   sys.procedures 
where 
   name like '%name_of_proc%'

This will tell you in which schema you will find the stored procedure in. Even, if you want to look into the code you can do so by running the following query.

select text 
from 
    syscomments c
    inner join sys.procedures p on p.object_id = c.id
where 
    p.name like '%name_of_proc%'

The text field contains the code of the stored procedure.

Let me know in the comments if you find this helpful or if you have any other ways to find the stored procedures.

Searching Lowercase data in MS SQL Server

Few days back I came across a requirement to fetch the records from the table having all lowercase letters. This was interesting scenario. The SQL Server database by default is set for case-insensitive. But, I need to do case-sensitive search. Case sensitive search in SQL Server can be achieved in two ways. Either by using COLLATE or by using BINARY_CHECKSUM().

  • COLLATE is the T-SQL clause used to define collation.
  • BINARY_CHECKSUM() is a built-in system function used to compare the binary check-sum value.

In this article I will show you how to use both the options. In addition to lowercase search, I’ll show you the uppercase search and mixed case search as well. 

To start with the experiment, lets create a table.

CREATE TABLE [dbo].[MyTecBits_Table_1](

[Sl_no] [int] IDENTITY(1,1) NOT NULL,

[Name] [varchar](50) NULL,

[Description] [varchar](500) NULL

) ON [PRIMARY]

GO

Insert records some with all lowercase, some with all uppercase and some with mixed case.

insert into MyTecBits_Table_1 values (‘MYTECBITS’,’THISWEBSITEHASBITSANDPIECESOFTECHNICALINFORMATION’)

insert into MyTecBits_Table_1 values (‘mytecbits’,’thiswebsitehasbitsandpiecesoftechnicalinformation’)

insert into MyTecBits_Table_1 values (‘MyTecBits’,’ThisWebSiteHasBitsAndPiecesOfTechnicalInformation’)

insert into MyTecBits_Table_1 values (‘MY TEC BITS’,’THIS WEB SITE HAS BITS AND PIECES OF TECHNICAL INFORMATION’)

insert into MyTecBits_Table_1 values (‘my tec bits’,’this web site has bits and pieces of technical information’)

insert into MyTecBits_Table_1 values (‘My Tec Bits’,’This Web Site Has Bits And Pieces Of Technical Information’)

SQL Server Case-Sensitive Search

 

Now our test table with test strings with different case types are ready for our experiment.

Fetching all lowercase records:

Fetching only the rows having all lowercase in one of the column using COLLATE method.

select * from MyTecBits_Table_1 where Name COLLATE Latin1_General_CS_AI = Lower(Name)

Fetching only the rows having all lowercase in one of the column using BINARY_CHECKSUM() method.

select * from MyTecBits_Table_1 where BINARY_CHECKSUM(Name) = BINARY_CHECKSUM(Lower(Name))

See the results for lower case search:

Fetching all uppercase records:

Similar to fetching the lowercase string, we can search for uppercase string just by changing the LOWER string function to UPPER string function. See the example below.

Fetching only the rows having all uppercase in one of the column using COLLATE method.

select * from MyTecBits_Table_1 where Name COLLATE Latin1_General_CS_AI = Upper(Name)

Fetching only the rows having all uppercase in one of the column using BINARY_CHECKSUM() method.

select * from MyTecBits_Table_1 where BINARY_CHECKSUM(Name) = BINARY_CHECKSUM(Upper(Name))

See the results for upper case search:

SQL Server Case-Sensitive Search

Fetching only the mixed case records:

Just like uppercase and lowercase sensitive search, we can search for mixed case records by combining upper and lowercase search conditions.

Fetching only the rows having mixed case in one of the column using COLLATE method.

select * from MyTecBits_Table_1 where Name COLLATE Latin1_General_CS_AI != Upper(Name) and Name COLLATE Latin1_General_CS_AI != Lower(Name)

Fetching only the rows having all mixed case in one of the column using BINARY_CHECKSUM() method.

select * from MyTecBits_Table_1 where BINARY_CHECKSUM(Name) != BINARY_CHECKSUM(Upper(Name)) and BINARY_CHECKSUM(Name) != BINARY_CHECKSUM(Lower(Name))

See the results for mixed case search:
