DOCERR: Incorrect Help Information on Number of Tables Open (159313)


The information in this article applies to:

  • Microsoft Visual FoxPro for Windows 5.0
This article was previously published under Q159313

SUMMARY

Visual FoxPro 5.0 Help has incorrect information about the Maximum number of tables that can be open at the same time.

MORE INFORMATION

In Help under Contents, click Technical Reference and System Information. Click the Visual FoxPro System Capacities topic and look at the entry under "Table and Index Files" for "Maximum # of tables open at one time." Following is the entry:

Maximum # of tables open at one time 2551

Visual FoxPro 5.0 does not have a limit of 2551 tables--the limit is much higher. To test that Visual FoxPro 5.0 allows you to have more than 2551 tables open at the same time run the following code: 
   SET ESCAPE ON
   SET TALK OFF
   CLEAR
   FOR n = 1 TO 3000
      lcTable = "TBL" + PADL(n,4,"0")
      CREATE TABLE (lcTable) ( smallfield C(1) )
      WAIT WINDOW "Creating " + lcTable nowait
   ENDFOR
The actual limit is approximately 65535 tables per data session. However, if you have more than 2000 tables open at one time, performance may be affected.
