It looks like the condition you're looking for is to split lines on
semicolons not contained in ' '. Perhaps you could do this with a
regular expression, but it might be simpler to write some parsing
code to do it. The following was tested on your example, and
appeared to work.
Charles Yeomans
Function SplitSQL(input as String) As String()
dim characters() as String = Split(input, "")
dim sqlStatements(-1) as String
dim lineStart as Integer = 0
dim isQuoted as Boolean = false
dim buffer(-1) as String
const delimiter = ";"
const quote = "'"
dim linebreaks as String = Encodings.UTF8.Chr(10) +
Encodings.UTF8.Chr(13)
for i as Integer = 0 to UBound(characters)
if InStr(linebreaks, characters(i)) > 0 then
continue
end if
If characters(i) = delimiter then
if not IsQuoted then
sqlStatements.Append Join(buffer, "")
redim buffer(-1)
else
buffer.Append characters(i)
end if
else
if characters(i) = quote then
isQuoted = not isQuoted
end if
buffer.Append characters(i)
end if
next
if UBound(buffer) > -1 then
sqlStatements.Append Join(buffer, "")
end if
return sqlStatements
End Function
