Filter illegal SQL characters to prevent SQL injection, etc. The experience idea inside mainly uses batch replacement, which is a good idea. Copy the code code as follows:
'************************************************ *
'Function name: R
'Function: Filter illegal SQL characters
'Parameter: strChar-----Character to be filtered
'Return value: filtered characters
'************************************************ *
Public Function R(strChar)

'strBadChar = $,#,',%,^,&,?,(,),<,>,[,],{,},/,/,;,:, & Chr(34) & , & Chr (0) &
strBadChar = +,',--,%,^,&,?,(,),<,>,[,],{,},/,/,;,:, & Chr(34) & , & Chr (0) &
arrBadChar = Split(strBadChar, ,)
tempChar = strChar
For I = 0 To UBound(arrBadChar)
tempChar = Replace(tempChar, arrBadChar(I), )
Next
tempChar = Replace(tempChar, @@, @)
R=tempChar
End Function
