Get all Tables with Column Names and Data types from SQL Server Database

In this post ,we will generate the script that will return us all the table names with column names and data type of those columns. We often need this information. Let's say we are going to prepare mapping document for load the data from Source Database to Destination database. We can get the list of all tables with column names and data types from Source Database and Destination Database and then paste in Excel and map the required input columns to output columns for ETL Process.

SELECT T.Name                   AS TableName,
       
Schema_name(T.schema_idAS SchemaName,
       
C.Name                   AS ColumnName,
       
Ty.Name                  AS ColumnDataType,
       
C.is_nullable            AS IsNullAble,
       
C.is_identity            AS IsIdentity 
FROM   sys.tables T
       
INNER JOIN sys.columns C
               
ON T.OBJECT_ID C.OBJECT_ID
       
INNER JOIN sys.types Ty
               
ON C.system_type_id Ty.system_type_id 
WHERE  T.is_ms_shipped 0 
ORDER  BY T.name 


How to find String in All Stored Procedures in SQL Server Database


We often have the situations where we want to find string in all the stored procedures in a database. Some of the situations are listed below

  • Find out how many stored procedure are using Cross Database Queries, so we want to search for Database name in all the stored procedures in a database.
  • Find out in how many stored procedure a table/view is used in a Database? This can be situation where we are planning to change the name of table/view and want to make sure if any Stored Procedure/s will be effected.
  • Find out a column name used in Stored Procedure/s in SQL Server Database.
  • Find out some comments in all the Stored Procedure to see who created those Stored Procedure, if Creator name is used in the comments.
and there could be more situations. SQL Server provide us system tables and views those store information and definition of objects for us so we can get information related to the objects such as tables,views,Stored Procedures,Triggers,Functions etc.

System.sql_modules and sys.syscomments system views can be used to dig into the definition of objects and search if any other object is used in the definition or not. Let's suppose if I am looking for comments in objects Creator Name=Aamir. I can use both system views to find out required information by using below queries.


SELECT OBJECT_NAME(OBJECT_IDAS ObjectName,
       
definition             AS ObjectDefinition
 FROM   sys.sql_modules 
WHERE  definition LIKE '%Creator Name=Aamir%'


 SELECT OBJECT_NAME(id) AS ObjectName,
       
TEXT AS ObjectDefinition 
FROM   sys.syscomments 
WHERE  TEXT LIKE '%Creator Name=Aamir%'
