Remove tab character (\t) from sqliteSeparator.

sqlite/ddlmod.go

Lines 58 to 79 in 7818dfd

	if sc := string(c); separatorRegexp.MatchString(sc) {
	if c == next {
	buf += sc // Skip escaped quote
	idx++
	} else if quote > 0 {
	quote = 0
	} else {
	quote = c
	}
	} else if quote == 0 {
	if c == '(' {
	bracketLevel++
	} else if c == ')' {
	bracketLevel--
	} else if bracketLevel == 0 {
	if c == ',' {
	result.fields = append(result.fields, strings.TrimSpace(buf))
	buf = ""
	continue
	}
	}
	}

When a tab character (\t) is present between the identifier and its type, separatorRegexp.MatchString(sc) can match and the code toggles the quote state incorrectly. The incorrect quote state causes the parser to ignore commas and therefore fail to split fields properly.

User Case Description

When parsing DDL that uses a tab character (\t) as whitespace between an identifier and its type, the parser can misinterpret the column list and return the wrong number of columns.

Reproduction DDL:

CREATE TABLE `test-e` (`field1`\ttext NOT NULL,`field2`\tinteger NOT NULL)

Expected result should have two columns:

• field1
• field2

Only one column is actually returned (the parser fails to split the column definitions correctly):

• field1

LGTM!

Pull request overview

This PR fixes a bug in the DDL parser where tab characters between column names and types were incorrectly treated as quote delimiters, causing the parser to fail to split column definitions properly.

Changes:

• Removed \t from sqliteSeparator to prevent tabs from being treated as quote characters
• Added a test case to verify that DDL with tabs between column identifiers and types is parsed correctly
