Re: [MS_AccessPros] Strange Errors when running query with a public function

 

hi Jim,

Access optimizes the query and saves it. Some of the ones you don't recognize are knocked out by the criteria but not all. 

Lots of information might be stored in Flags -- once you figure out why they are there, you can perhaps see a pattern but it might be in a different field too.  Much of what I have figured out about the undocumented stuff is by experimentation on what I had to look at it with. I am not looking at your database, so I don't know what has been done ... but ...

Do you have multi-value or attachment fields or other complex data types?

respectfully,
crystal

I changed the query to the following SQL below and it worked with the new code. I am still confused what those queries are doing there. they do not show up in the nav pane.


SELECT msysObjects.Name, GetSQL([Name]) AS [SQL], Left([SQL],(InStr(1,[SQL]," ")-1)) AS [Query Type], "Drivers License Database" AS [Database Name], msysObjects.Flags

Crystal,

So I am really trying to figure this out. All 28 or so databases use the original code and query with no problem. This last database I have created a new database and moved all objects to it, I have done all that has been suggested and still it is not working. But after trying your suggestion of the flag field. I created a new query with just the name and the flag field. I noticed something new. everyone of the queries that have this long weird character string making a duplicate has one interesting characteristic. The flag field has a value of -2147352320 and the query that is the correct one has a value in the flag field as 262144.

here is a more complete list of the Flags*:

0 Select query dbQSelect
16 Crosstab query dbQCrosstab
32 Delete query dbQDelete
48 Update query dbQUpdate
64 Append query dbQAppend
80 Make-table query dbQMakeTable
96 DDL, Data-definition language query dbQDDL

144 Bulk operation query dbQSPTBulk
160 Compound query dbQCompound

... I am guessing that 8 (not in list above) is Hidden. Not sure if Flags uses bit-math.

Hi Jim,

perhaps the problem is recurrent use of CurrentDb ... perhaps try:

Option Compare Database
Option Explicit

Dim m_db As dao.Database

Public Function GetSQL(strQueryName As String) as string
's4p
       If m_db Is Nothing Then
          Set m_db = CurrentDb
       end if
      GetSQL = m_db.QueryDefs(strQueryName).SQL & ""
End Function

public sub ReleaseTheDatabase
   Set m_db = Nothing
end sub

~~~~
then when the query is done, run ReleaseTheDatabase

I changed the return to a string because if Null is returned, your QueryType equation will have an error with Left -- maybe change to Left([SQL] & "  " ...

However, maybe you want to get the query type another way?

use the Flags field of MSysObjects to determine query type

for instance:
0 = Select
32 = Delete
48 = Update
64 = Append
80 = MakeTable
128 = Union

other bits:
8 = Hidden?

Jim,


The msysobjects table isn't documented by Microsoft although many of us have used it. There could be near duplicates from internal processes that we have no idea about.


I'm not sure what you mean by "How does a query run but have errors?"

Duane,

In database 2 I figured out why the error comes up. But confused at why it gives the error. Apparently there is a macro and it runs a series of queries. 2 of the queries are the ones with ambiguous joins. Although they run in the macro and alone. But will not let me open the queries in design view because of the ambiguous join error. How does a query run but have errors?

I changed the joins and they worked for the second database.


But the first database I am getting a list of the queries but they are being duplicated like the following

qry6To7Points
qry6To7Points_F31DBFE61EC14C9CBA6BB5A50544BA69

qry8OrMorePoints
qry8OrMorePoints_951765DA04F142C6BB3DF1CE020234EC

Duane,

I did as you instructed for both databases and received the same errors respectively for both databases.

Could the issue actually be the query syntax of each of the queries?

Is there another sql statement that I do not need the module?

Jim,


This sounds like some form of corruption. I would make a backup of the database and then Repair and Compact. If the errors still occur, create a new database and import all of the objects into it.


Regards,

Duane

Hello all,


This morning I have come across 2 strange errors that only happens on 2 different databases for a process that is on 20 other databases and work correctly.


I am not sure why these two databases are causing the issues.


I would appreciate any assistance with this crazy problem.


Thank You


Jim Wagner




I have a public function


Option Compare Database


'SQL Database statements


Public Function GetSQL(strQueryName As String)
'GetSQL = CurrentDb.QueryDefs(strQueryName).SQL
End Function


Then a query

SELECT msysObjects.Name, GetSQL([Name]) AS [SQL], Left([SQL],(InStr(1,[SQL]," ")-1)) AS [Query Type], "Drivers License Database" AS [Database Name]
FROM msysObjects
WHERE (((msysObjects.Name) Not Like '~*') AND ((msysObjects.type)=5));


Database 1


The error for this database

is a run-time error 3265

Item not found in this collection.


_________________________________________


Database 2

The next database has the same public function and the same query


but the error is different


it is  run-time error '3258'

The SQL statement could not be executed because it contains  ambiguous joins. To force one of the joins to be performed first, create a separate query that performs the first join and then include the query in your SQL statement.


It does not let me out of the error.
