| Iciql | JaQu | |
|---|---|---|
| core | ||
| deployment | small, discrete library | depends on H2 database jar file |
| databases | H2, HSQL, Derby, MySQL, PostreSQL, and SQLite | H2 only |
| logging | console, SLF4J, or custom logging | console logging |
| exceptions | always includes generated statement in exception, when available | -- |
| column mappings | wildcard queries index result sets by column name | all result sets built by field index this can fail for wildcard queries |
| savepoints | bulk operations (insert, update, delete) use savepoints with rollback in the event of failure | -- |
| syntax and api | ||
| VIEWs | create readonly views either from a class definition or from a fluent statement | -- |
| Foreign Key Constraints | model classes may be annotated with foreign key constraints | -- |
| dynamic queries | methods and where clauses for dynamic queries that build iciql objects | -- |
| DROP | syntax to drop a table or view | |
| BETWEEN | syntax for specifying a BETWEEN x AND y clause | -- |
| (NOT) IN | syntax (oneOf, noneOf) for specifying a (NOT) IN clause | -- |
| compound nested conditions | WHERE (x = y OR x = z) AND (y = a OR y = b) | -- |
| dynamic DAOs | DAO interfaces with annotated statements may be declared and dynamically generated | -- |
| types | ||
| primitives | fully supported | -- |
| enums | fully supported | -- |
| DECIMAL(length,scale) | can specify length/precision and scale | -- |
| BOOLEAN | flexible mapping of boolean as bool, varchar, or int | -- |

| UUID | fully supported (H2 only) | -- |
| configuration | ||
| DEFAULT values | set from annotation, default object values, or Define.defaultValue() | set from annotations |
| Interface Configuration Mapped Fields |

all public fields are mapped fields are ignored by reducing their scope |
| Index names | can be set | -- |
