Conclusion

  1. Using Microsoft Visual Basic 2008 Express to build (publish) an installer (setup.exe), there are many limitations:-
    1. unable to specify the path to install files; by default it install the exe file into “..\AppData\Local\Apps” folder

Renaming Column Name will Affect PHPRunner

If column name is renamed via PHPMyAdmin or PHPRunner, the records will be missing from the list page (tellow table) despite there are 3528 records:-

 

The following solutions DOES NOT work:-

  1. Remove all fields in stock card’s list page and add them all again.
  2. Delete current list page and add a new list page.
  3. Remove the table and add it again.

 

The only solution is to re-build the PHP project from scratch.

The possible root cause is the PHP project was built using old version (e.g. version 10.3) or trial version of PHPRunner. Then column name is renamed in the new version of PHPRunner, e.g. version 10.4.

How to Remove Space using SQL Statement

Problem: there are leading space and trailing space in the records.

  • leading space
  • trailing space

 

Solution: to remove leading space, e.g. ” EKONOR-25M”, use

UPDATE `Stock_Card-20220218` SET `Item_ID`=TRIM(`Item_ID`) WHERE `Item_ID` LIKE '% ';
BEFORE AFTER

 

Solution: to remove trailing space, e.g. “EKONOR-25M “, SQL statement (“Trim”, “Rtrim”, “Replace”) CANNOT be used. The only way is to delete it manually.
