Question

I have this string here:

CREATE UNIQUE INDEX index555 ON
SOME_TABLE
(
    SOME_PK          ASC
);

I want to match across the multiple lines and match the SQL statements (all of them, there will be many in 1 large string)… something like this, however I am only getting a match on CREATE UNIQUE INDEX index555 ON

(CREATE\s.+;)

note: I am trying to accomplish this in java if it matters.

You need to use DOTALL and MULTILINE flags when compiling a regular expression. Here is a Java code example:

import java.util.regex.*;

public class test
{
    public static void main(String[] args)
    {
        String s =
        "CREATE UNIQUE INDEX index555 ON\nSOME_TABLE\n(\n    SOME_PK          ASC\n);\nCREATE UNIQUE INDEX index666 ON\nOTHER_TABLE\n(\n    OTHER_PK          ASC\n);\n";

        Pattern p = Pattern.compile("([^;]*?('.*?')?)*?;\\s*", Pattern.CASE_INSENSITIVE | Pattern.DOTALL | Pattern.MULTILINE);

        Matcher m = p.matcher(s);

        while (m.find())
        {
        System.out.println ("--- Statement ---");
        System.out.println (m.group ());
        }
    }
}

The output will be:

--- Statement ---
CREATE UNIQUE INDEX index555 ON
SOME_TABLE
(
    SOME_PK          ASC
);

--- Statement ---
CREATE UNIQUE INDEX index666 ON
OTHER_TABLE
(
    OTHER_PK          ASC
);
