Need to fetch ID using stored procedure in SQL Server - sql

Question

CREATE TABLE myTable99 (TABLE_NAME sysname, COLUMN_NAME sysname, Occurs int)
GO
SET NOCOUNT ON
DECLARE #SQL varchar(8000),
#TABLE_NAME sysname,
#COLUMN_NAME sysname,
#Sargable varchar(80),
#Count int
SELECT #Sargable = 'PS'
DECLARE insaneCursor CURSOR FOR
SELECT c.TABLE_NAME, c.COLUMN_NAME
FROM INFORMATION_SCHEMA.Columns c INNER JOIN INFORMATION_SCHEMA.Tables t
ON t.TABLE_SCHEMA = c.TABLE_SCHEMA AND t.TABLE_NAME = c.TABLE_NAME
WHERE c.DATA_TYPE IN ('char','nchar','varchar','nvarchar','text','ntext')
AND t.TABLE_TYPE = 'BASE TABLE'
OPEN insaneCursor
FETCH NEXT FROM insaneCursor INTO #TABLE_NAME, #COLUMN_NAME
WHILE ##FETCH_STATUS = 0
BEGIN
SELECT #SQL = 'INSERT INTO myTable99 (TABLE_NAME, COLUMN_NAME, Occurs) SELECT '
+ '''' + #TABLE_NAME + '''' + ','
+ '''' + #COLUMN_NAME + '''' + ','
+ 'COUNT(*) FROM [' + #TABLE_NAME
+ '] WHERE [' + #COLUMN_NAME + '] Like '
+ ''''+ '%' + #Sargable + '%' + ''''
--SELECT #SQL
EXEC(#SQL)
IF ##ERROR <> 0
------ <> means Not Equal To
BEGIN
SELECT #SQL
SELECT * FROM INFORMATION_SCHEMA.Columns WHERE TABLE_NAME = #TABLE_NAME
GOTO Error
END
FETCH NEXT FROM insaneCursor INTO #TABLE_NAME, #COLUMN_NAME
END
SELECT * FROM myTable99 WHERE Occurs <> 0
Error:
CLOSE insaneCursor
DEALLOCATE insaneCursor
GO
DROP TABLE myTable99
GO
SET NOCOUNT OFF
The following stored procedure will search for the string 'PS' and will return the COLUMN_NAME and TABLE_NAME but I want the ID value of the PS in corresponding column
ex:
ID NAME
2 PW
3 PS
now stored procedure only returns COLUMN_NAME,TABLE_NAME but I need the ID that is 3 when I search for string 'PS' along with COLUMN_NAME and TABLE_NAME
I tried with
SELECT #SQL = 'INSERT INTO myTable99 (TABLE_NAME, COLUMN_NAME, Occurs) SELECT *'
+ 'FROM [' + #TABLE_NAME
+ '] WHERE [' + #COLUMN_NAME + '] Like '
+ ''''+ '%' + #Sargable + '%' + ''''
but the stored procedure returned all table and column name in database even if the string is not found in table
myTable99
TABLE_NAME COLUMN_NAME Occurs
project projectname 2
task name 1
Now I need a new column with name ID which fetches the ID of the projectname 'PS' in table project
Expected result:
Suppose table Project has PS entry
Table name: Project
Columns:
ID projectname
2 PR
3 PS
Now the stored procedure will return the Table_Name=Project,column_Name=projectname but not the Id, I need ID of the string PS that is 3
Result: when I search for string='PS'
ID TABLE_NAME COLUMN_NAME Occurs
3 Project projectname 1

Your question is not very clear, I think you need to bring the projectId along with rest of the columns in myTable99. You can do following.
--++++++++++++++++++++++++++++++++++++++++++++++++
--Before/after your cursor (not within the cursor)
DECLARE #ProjectId INT
--Assuming projectName as a unique constraint
SELECT #ProjectId = ProjectId
FROM yourProjectTable
WHERE projectName = #Sargable
--++++++++++++++++++++++++++++++++++++++++++++++++
--At the end, replace your select query with
SELECT TABLE_NAME, COLUMN_NAME, Occurs, #ProjectId ProjectId
FROM myTable99
WHERE Occurs <> 0
