SQL Server Search Column Name in All Tables with Code Examples
SQL Server is a relational database management system that is widely used to store and manage large amounts of data. One of the common tasks in SQL Server is to search for a particular column name in all tables of a database. This article will provide a step-by-step guide to search for a column name in all tables of a SQL Server database along with code examples.
Step 1: Connect to the SQL Server database
Before you start searching for a column name in all tables, you need to connect to the SQL Server database. You can use the SQL Server Management Studio (SSMS) to connect to the database. Once connected, you can execute the following T-SQL script to search for a column name in all tables.
Step 2: T-SQL script to search for a column name in all tables
The following T-SQL script can be used to search for a column name in all tables of a database:
DECLARE @ColumnName VARCHAR(100) = 'column_name'
DECLARE @SearchString VARCHAR(100) = '%' + @ColumnName + '%'
SELECT
t.name AS TableName,
c.name AS ColumnName
FROM
sys.tables t
INNER JOIN sys.columns c ON t.object_id = c.object_id
WHERE
c.name LIKE @SearchString
ORDER BY
TableName, ColumnName
In the above script, you need to replace 'column_name' with the actual column name you want to search for. The script will return the table name and column name for all the tables where the column name matches the search string.
Step 3: Example
Let's consider an example to understand the above T-SQL script. Consider a database with the following tables:
Table 1: Employee
Columns: EmployeeID, EmployeeName, EmployeeAge
Table 2: Department
Columns: DepartmentID, DepartmentName, EmployeeID
Table 3: Salary
Columns: SalaryID, EmployeeID, SalaryAmount
If you want to search for the column name 'EmployeeID', you can execute the following T-SQL script:
DECLARE @ColumnName VARCHAR(100) = 'EmployeeID'
DECLARE @SearchString VARCHAR(100) = '%' + @ColumnName + '%'
SELECT
t.name AS TableName,
c.name AS ColumnName
FROM
sys.tables t
INNER JOIN sys.columns c ON t.object_id = c.object_id
WHERE
c.name LIKE @SearchString
ORDER BY
TableName, ColumnName
The above script will return the following result:
TableName ColumnName
Department EmployeeID
Employee EmployeeID
Salary EmployeeID
Conclusion
In this article, you have learned how to search for a column name in all tables of a SQL Server database. The T-SQL script provided in this article can be used to search for a column name in all tables of a database. The script returns the table name and column name for all the tables where the column name matches the search string.
SQL Server is a powerful database management system that provides many features to manage and manipulate data. Some of the adjacent topics related to searching for a column name in all tables are:
- Searching for a table name in a database: In SQL Server, you can search for a table name in a database by using the following T-SQL script:
DECLARE @TableName VARCHAR(100) = 'table_name'
DECLARE @SearchString VARCHAR(100) = '%' + @TableName + '%'
SELECT
name
FROM
sys.tables
WHERE
name LIKE @SearchString
ORDER BY
name
In the above script, you need to replace 'table_name' with the actual table name you want to search for. The script will return the table name for all the tables where the table name matches the search string.
- Searching for a stored procedure in a database: In SQL Server, you can search for a stored procedure in a database by using the following T-SQL script:
DECLARE @ProcedureName VARCHAR(100) = 'procedure_name'
DECLARE @SearchString VARCHAR(100) = '%' + @ProcedureName + '%'
SELECT
name
FROM
sys.procedures
WHERE
name LIKE @SearchString
ORDER BY
name
In the above script, you need to replace 'procedure_name' with the actual stored procedure name you want to search for. The script will return the stored procedure name for all the stored procedures where the stored procedure name matches the search string.
- Searching for a view in a database: In SQL Server, you can search for a view in a database by using the following T-SQL script:
DECLARE @ViewName VARCHAR(100) = 'view_name'
DECLARE @SearchString VARCHAR(100) = '%' + @ViewName + '%'
SELECT
name
FROM
sys.views
WHERE
name LIKE @SearchString
ORDER BY
name
In the above script, you need to replace 'view_name' with the actual view name you want to search for. The script will return the view name for all the views where the view name matches the search string.
In conclusion, searching for a column name in all tables is just one of the many tasks you can perform in SQL Server. By using the T-SQL scripts provided in this article, you can easily search for different objects in a SQL Server database.
