PR Summary

• Addition of new file AbstractExpressionBuilder.php
  A new file that contains the AbstractExpressionBuilder class is added to help in the creation of various expressions for database queries.

• Removal of ExpressionBuilder.php
  The ExpressionBuilder class, previously used for building expressions, is no longer needed. The file containing this class was deleted.

• Changes in AbstractDQLQueryBuilder.php
  Several method modifications were made to simplify the building of queries. A significant change is that these methods now return a string rather than being void, and also receive additional parameters. The methods also utilize the quoter property for quoting column names.

  This new file has the AbstractSqlParser class, which assists in parsing SQL statements and extracting placeholders from them.

• Test adjustments in AbstractQueryBuilderTest.php & CommonCommandTest.php
  Tests were adjusted to now compare the quoted SQL output, a change to improve test accuracy. Also, several method parameters were modified to streamline and refine the testing process.

• Addition of AbstractSqlParserTest.php
  This file was added to contain test cases for the new AbstractSqlParser class.

• Modifications in QueryBuilderTest.php
  Similar to the other test modifications, this file had changes to test parameters and comparisons of quoted SQL output.

• Addition of tests and cases in CommandProvider.php
  New test cases, with nested expressions and new parameters, were added to improve testing comprehensiveness.

• Addition of new files
  Several new files, each containing specific classes and functionalities have been added. These include SqlParserProvider.php, DQLQueryBuilder.php, ExpressionBuilder.php, and SqlParser.php. These contribute to broadening the system's functionalities.

Could SQL contain unicode strings?

[Tigrov]

Yes, I'll check this.

[Tigrov]

No problems with UTF-8 or any single-byte encoding.

Should it support other multibyte encodings? If should, it could be a problem to pass that encoding to the parser.
