When attempting to publish a workflow, publish a form, or run an NWAdmin command you receive the following message:
Could not find stored procedure 'STOREDPROCEDURE'
Missing stored procedure messages are in relation to Nintex databases not being updated properly. To ensure your databases are updated, run the following commands in the SharePoint Management Shell or Powershell with Add-PSSnapin Microsoft.SharePoint.PowerShell:
For Nintex Workflow Databases: NWAdmin.exe -o UpgradeDatabases
For Nintex Forms Databases: Install-NFService Upgrade-NFService
Examples include but are not limited to:
NWAdmin -o DetachDatabase - Could not find stored procedure 'GetExtIOSiteMapping'
Publishing a Nintex Form - Could not find stored procedure 'NM_DeleteFormByContentTypeAndList'
Publishing a Nintex Workflow - Server was unable to process request. ----> Cound not find stored procedure 'NM_DeleteFormByWorkflowBaseID'
These errors indicate that a stored procedure is not present in a database. Running the relevant commands updates/checks the database schema and should recreate the stored procedure.
