Hello, I'm hoping someone has come across a similar issue and may have a solution for me.

Currently have the following table setup (only showing affected columns). Column list is as follows:

Table Name: tblActivity (tblDenyActivity)
DenyDateUserID
DenyDate
InvalidDate

Table Name: tblUserData
UserID

Table Name: tblUserSkillset
UserID
SkillsetTypeID

Table Name: tblSkillsetType
SkillsetTypeID
SkillSetType
SQLSnippet

SELECT tblDenyActivity.DenyDateUserID, tblDenyActivity.DenyDate FROM dbo.tblActivity AS tblDenyActivity INNER JOIN
dbo.tblUserData ON tblDenyActivity.DenyDateUserID = dbo.tblUserData.UserID AND tblDenyActivity.InvalidDate IS NULL INNER JOIN dbo.tblUserSkillset ON dbo.tblUserData.UserID = dbo.tblUserSkillset.UserID INNER JOIN dbo.tblSkillsetType ON dbo.tblUserSkillset.SkillsetTypeID = dbo.tblSkillsetType.SkillsetTypeID
WHERE (dbo.tblSkillsetType.SQLSnippet)

The column SQLSnippet will contain something like the following (DenyDate IS NOT NULL AND DATEDIFF(dd,DenyDate,GETDATE()) > 31)

So my end result would be:

SELECT tblDenyActivity.DenyDateUserID, tblDenyActivity.DenyDate FROM dbo.tblActivity AS tblDenyActivity INNER JOIN
dbo.tblUserData ON tblDenyActivity.DenyDateUserID = dbo.tblUserData.UserID AND tblDenyActivity.InvalidDate IS NULL INNER JOIN dbo.tblUserSkillset ON dbo.tblUserData.UserID = dbo.tblUserSkillset.UserID INNER JOIN dbo.tblSkillsetType ON dbo.tblUserSkillset.SkillsetTypeID = dbo.tblSkillsetType.SkillsetTypeID
WHERE (DenyDate IS NOT NULL AND DATEDIFF(dd,DenyDate,GETDATE()) > 31)

Has anyone ever tried to do anything like this?

The only way to do that is to use dynamic SQL, build up the final query and then use sp_executeSQL to run it.

Be aware of the downsides of dynamic SQL and watch for SQL injection.
