Full Changelog: 1.1.0...1.2.0

PostgreSQL dialect with ILIKE and RETURNING support

• Add PostgreSqlDialect extending AbstractSqlDialect:
  double-quote identifier quoting, supportsReturning()=true,
  appendConditionFragment override for ILIKE/NOT ILIKE
• Register SqlDialect.POSTGRESQL constant in SqlDialect interface
• Add ILIKE and NOT_ILIKE to Operator enum (PostgreSQL-only operators)
• Add supportsReturning() hook to AbstractSqlDialect;
  renderDelete() now appends RETURNING clause when the hook returns true

RETURNING clause support to DML builders

• Add returningColumns field + getter/setter to Query
• DeleteBuilder.returning(String... columns): passed through Query
  to AbstractSqlDialect.renderDelete() via supportsReturning() hook
• InsertBuilder.returning(String... columns): appended inline to SQL
• UpdateBuilder.returning(String... columns): appended inline to SQL

whereILike / orWhereILike builder methods

• QueryBuilder.whereILike(column, value): ILIKE condition with AND connector
• QueryBuilder.orWhereILike(column, value): ILIKE condition with OR connector
• SelectBuilder.whereILike(column, value): ILIKE condition with AND connector
  (follows existing whereLike pattern; no orWhere* in SelectBuilder)

ColumnType for type-safe column definitions

• Add ColumnType final class with 25 fixed-type constants (TINYINT through
  UUID), 7 parameterised factory methods (varChar, charType, decimal,
  numeric, binary, varBinary, timestamp), and 4 chainable modifier methods
  (notNull, unique, autoIncrement, defaultValue)
• Add CreateBuilder.column(String, ColumnType) overload; delegates to the
  existing column(String, String) via ColumnType.toSql(), fully backward
  compatible
• Add ColumnTypeTest: 32 tests covering constants, factories, modifiers,
  chaining, and CreateBuilder integration

Per-type shorthand classes

Each class in the new col package wraps a single ColumnType constant or
factory method behind a concise name and a uniform of() / of(params)
factory. Developers can use a wildcard import to write:

import com.github.ezframework.javaquerybuilder.query.builder.col.*;

.column("id",         Int.of().notNull().autoIncrement())
.column("username",   VarChar.of(64).notNull().unique())
.column("price",      Decimal.of(10, 2))
.column("created_at", Timestamp.of())

instead of prefixing every type with ColumnType.

Classes added (31 total):
Fixed types: TinyInt, SmallInt, Int, BigInt, SqlFloat, SqlDouble,
Real, Bool, Text, TinyText, MediumText, LongText, Clob,
Blob, TinyBlob, MediumBlob, LongBlob, Date, Time, DateTime,
Json, Serial, BigSerial, Uuid
Parameterised types: Timestamp (overloaded of() / of(int)),
VarChar, Char, Decimal, Numeric, Binary, VarBinary

• SqlFloat / SqlDouble / Bool named to avoid shadowing java.lang types
  when the package is wildcard-imported
• ColTypesTest: 34 tests covering all classes and modifier chaining

Integrate QueryBuilderDefaults into all SELECT/DELETE builders

QueryBuilder, DeleteBuilder, and SelectBuilder each gain:

• A queryBuilderDefaults field initialised from QueryBuilderDefaults.global()
  at construction time (snapshot semantics, not live).
• A withDefaults(QueryBuilderDefaults) fluent method for per-instance
  override without touching the global.

Behavioural changes when a non-default QueryBuilderDefaults is active:

• Dialect: buildSql() / build() null-fallback now routes to the
  configured dialect instead of hardcoded SqlDialect.STANDARD.
• Default columns: rendered when no explicit select() columns are set.
• Default limit / offset: applied when builder sentinel (-1) is present
  and the defaults carry a non-negative value (explicit wins).
• LIKE wrapping: SelectBuilder.whereLike() now honours likePrefix /
  likeSuffix (previously had no wrapping at all, aligned with
  AbstractSqlDialect behaviour).

Added

Subquery support (feature/subquery — PR #21)

• New JoinClause model class representing a JOIN entry targeting either a plain table or a derived-table subquery (INNER / LEFT / RIGHT / CROSS).
• New ScalarSelectItem model class representing a (SELECT ...) AS alias item in the SELECT clause.
• Query extended with four new fields: fromSubquery, fromAlias, joins, selectSubqueries.
• QueryBuilder new fluent methods:
  • whereInSubquery(String column, Query subquery) — WHERE col IN (SELECT ...)
  • whereEqualsSubquery(String column, Query subquery) — WHERE col = (SELECT ...)
  • whereExistsSubquery(Query subquery) — WHERE EXISTS (SELECT ...)
  • whereNotExistsSubquery(Query subquery) — WHERE NOT EXISTS (SELECT ...)
  • fromSubquery(Query subquery, String alias) — FROM (SELECT ...) AS alias
  • joinSubquery(Query subquery, String alias, String onCondition) — INNER JOIN (SELECT ...) AS alias ON ...
  • selectSubquery(Query subquery, String alias) — appends (SELECT ...) AS alias to the SELECT list
• DeleteBuilder new fluent methods:
  • whereInSubquery(String column, Query subquery) — DELETE WHERE col IN (SELECT ...)
  • whereExistsSubquery(Query subquery) — DELETE WHERE EXISTS (SELECT ...)
• Operator enum: added EXISTS_SUBQUERY and NOT_EXISTS_SUBQUERY values.
• Deterministic subquery parameter ordering contract in AbstractSqlDialect.render(): scalar SELECT subquery params → FROM subquery params → JOIN subquery params → WHERE condition params.
• New test classes: SubqueryConditionTest, ExistsSubqueryTest, FromSubqueryTest, JoinSubqueryTest, ScalarSelectSubqueryTest, NestedSubqueryParamOrderTest, DeleteSubqueryIntegrationTest.
• SqlExecutionMatrixTest — real SQLite integration tests covering all builder operations across standard, MySQL, and SQLite dialects.
• Test dependencies added: junit-jupiter-params 6.0.3, sqlite-jdbc 3.46.1.3 (test scope).

Dialect-aware DELETE rendering (feature/delete-from — PR #20)

• SqlDialect interface: new renderDelete(Query query) method.
• AbstractSqlDialect.renderDelete(Query) — standard implementation rendering DELETE FROM <table> WHERE ... with full parameter binding via the shared appendWhereClause helper.
• AbstractSqlDialect.supportsDeleteLimit() — protected hook; default false. Override to enable dialect-specific DELETE ... LIMIT.
• MySqlDialect: overrides supportsDeleteLimit() → true.
• SqliteDialect: overrides supportsDeleteLimit() → true.
• AbstractSqlDialectDeleteTest — new test class covering DELETE rendering, dialect quoting, LIMIT behaviour, and IN-clause placeholder count.

Changed

• DeleteBuilder.build(SqlDialect) refactored: removed inline SQL string building; now delegates entirely to SqlDialect.renderDelete(Query).
• AbstractSqlDialect.appendWhereClause() and appendConditionFragment() promoted from private to protected to allow reuse in renderDelete.
• Condition.matches() updated: guards IN and NOT_IN operators against subquery values (returns false when value is a Query instance, since subqueries cannot be evaluated in-memory).
• CI: replaced JaCoCo PR-comment reporter (madrapps/jacoco-report) with codecov/codecov-action@v5.

Documentation

• README updated with subquery usage examples (scalar SELECT, FROM derived table, JOIN subquery, WHERE IN subquery, WHERE EXISTS).
• README updated with renderDelete documentation and DELETE LIMIT dialect behaviour.
• README artifact ID corrected.
• Version bumped to 1.0.4 in pom.xml.

Added

• SelectBuilder: fluent builder for SQL SELECT statements with support for
  columns, WHERE conditions, ORDER BY, GROUP BY, HAVING, LIMIT, OFFSET, and DISTINCT
• CreateBuilder: fluent builder for SQL CREATE TABLE statements with support for
  columns, primary keys, and IF NOT EXISTS
• QueryBuilder: unified static entry point for all builder types
  • select(), from() for SELECT queries
  • insert(), insertInto(table) for INSERT queries
  • update(), update(table) for UPDATE queries
  • delete(), deleteFrom(table) for DELETE queries
  • createTable(), createTable(table) for CREATE TABLE queries
• Table-shortcut overloads on QueryBuilder: insertInto, deleteFrom, update(table),
  and createTable(table) to set the target table in a single call
• whereIn support on DeleteBuilder

Fixed

• DeleteBuilder: restored missing build() and build(SqlDialect) methods whose
  Javadoc was malformed and consumed the method body
• DeleteBuilder: added missing imports (Connector, Operator, SqlDialect, SqlResult, Map)
• DeleteBuilder: added appendDmlCondition helper to handle all comparison operators
  and resolve cyclomatic complexity violation; fixed duplicate /** on handleBetweenOperator
• CreateBuilder: repaired malformed class-level Javadoc that contained an embedded
  method body, and fixed unclosed build(SqlDialect) Javadoc comment
• QueryBuilder: removed redundant same-package imports, fixed import ordering,
  added complete Javadoc on all public API methods

• Fixed issue in Jitpack publish CI
