Hi all,

I have been trying to save a record with 2 of the fields being uniqueidentifier on MSSQL.

The error I have been getting is
com.microsoft.sqlserver.jdbc.SQLServerException: Conversion failed when converting from a character string to uniqueidentifier.

the data comes out of a MAP
B4X:
paramsInfo(0) =info.Get("masteritem")

The full sub is

B4X:
Sub saveiteminfo(sql As SQL,info As Map)
    
    Dim querySaveInfo As String = utils.prepareInsertQuery($"
                    INSERT INTO assets (
                           [id]
                          ,[customer_id]
                          ,[insurance_company_id]
                          ,[item_name]
                          ,[item_description]
                          ,[item_cost]
                          ,[policy_number]
                          ,[serial_number]
                          ,[claim_number]
                          ,[brand]
                          ,[extra_info]
                    )
                "$)
    
    Dim paramsInfo(querySaveInfo.Length - querySaveInfo.Replace("?","").Length) As String
    paramsInfo(0) =info.Get("masteritem")
    paramsInfo(1) =info.Get("user_id")
    paramsInfo(2) =info.Get("insurancecomany")
    paramsInfo(3) =info.Get("model")
    paramsInfo(4) =info.Get("description")
    paramsInfo(5) =0
    paramsInfo(6) =info.Get("policynumber")
    paramsInfo(7) =info.Get("serial")
    paramsInfo(8) =""
    paramsInfo(9) =info.Get("brand")
    paramsInfo(10) =""
    sql.ExecNonQuery2(querySaveInfo,paramsInfo)
    sql.close

End Sub



Have tried to change it to Object instead of string but still the same issue

You should really show the full SQL insert statement as your posted code is not very helpful. What are the values your are trying to save ? If you have the full SQL statement you can use SQL Management console to exec the query to debug it.

I did post the full insert statement. Please explain why you do not think it is the full code ? It is the full code in my program for insert.


As an example , here are the keys and values

Key: user_id
Value: 95AC6CBD-1640-41F5-9727-393EFC97ADD9
Key: masteritem
Value: F33EFE3D-54CF-988D-9A38-364D051BC966
Key: brand
Value: hg
Key: model
Value: gg
Key: serial
Value: hh
Key: insurancecomany
Value: gg

This is the code i used in smss to test and it works there

B4X:
  INSERT INTO dbo.assets
  ([id], [customer_id],[item_name])
VALUES
  ('95AC6CBD-1640-41F5-9727-393EFC97ADD9',
   'F33EFE3D-54CF-988D-9A38-364D051BC966',
   'test' );

The error you're getting seems to indicate that you are not passing a valid string that can be turned into a unique identifier as expected by the server:
I'd add a log statement and see exactly what you're passing as parameters. Unless you have a real need for unique id type, I'd stick to INT or BIGINT as your key values. See: Primary Keys: IDs versus GUIDs (codinghorror.com)
