Introduction
StoredProcedureGenerator is a powerful tool to generate Insert, Update, Delete, and Select Stored Procedures (whichever you want) for selected tables for a particular database. You can connect to any SQL Server DB server.
Description
Select your DB server from the combo box. If you could not find your desired server, type it yourself. Check the radio-button to specify whether the DB server is on Windows Authentication or SQL Server Authentication. If it is SQL Server authentication, enter the username and password. You will be able to see all the databases on the selected database server. Select the desired database. You can test your connection by clicking Test Connection. Click the OK button. You would be able to see all the tables of the selected database in a grid. Check the tables for which you want to generate Stored Procedures. If you want this for all tables, select the checkbox on the top of the tables name (besides Name). Select the folder path where you want to save the script file. The system will give the name for the script file (StoredProcedures.sql).
Select which type of Stored Procedures you want (Insert, Update etc.). Click the OK button to generate the script file on the selected path. The system will give the names for the Stored Procedures itself according to the following format tablename_type (where type is Insert, Update etc). For example Person_Insert.
Using the Code
The following code generates the script files for creating Stored Procedures:
private void GenerateStoredProcedures()
{
string sp = "";
if (tablesDataGridView.Rows[0].Cells["Catalog"] != null)
{
sp = "USE " + tablesDataGridView.Rows[0].Cells["Catalog"].Value.ToString() +
"\n";
sp += "GO \n";
}
if (connection.State == ConnectionState.Closed)
{
connection.Open();
}
foreach (string item in spCheckedListBox.CheckedItems)
{
switch (item)
{
case "Insert":
sp+=GenerateInsertStoredProcedure();
break;
case "Update":
sp+=GenerateUpdateStoredProcedure();
break;
case "Delete":
sp+=GenerateDeleteStoredProcedure();
break;
case "Select":
sp+=GenerateSelectStoredProcedure();
break;
}
}
connection.Close();
StreamWriter writer = new StreamWriter(filePathTextBox.Text +
"\\StoredProcedures.sql");
writer.Write(sp);
writer.Close();

Future Enhancements
I have plans to make it more generic so that it can generate Stored Procedures for other databases.
