## What type supported at now

| Data type | Value type in Java | Description |
|:----------|:----------|:------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| string | `java.lang.String` | string |
| boolean | `java.lang.Boolean` |boolean |
| tinyint | `java.lang.Byte` | -128 to 127 regular. 0 to 255 unsigned*. Specify the maximum number of digits in parentheses. |
| smallint | `java.lang.Short` | -32768 to 32767 General. 0 to 65535 unsigned*. Specify the maximum number of digits in parentheses. |
| int | `java.lang.Integer` | All numbers from -2,147,483,648 to 2,147,483,647 are allowed. |
| bigint | `java.lang.Long` | All numbers between -9,223,372,036,854,775,808 and 9,223,372,036,854,775,807 are allowed. |
| float | `java.lang.Float` | Float-precision numeric data from -1.79E+308 to 1.79E+308. |
| double | `java.lang.Double` | Double precision floating point. Handle most decimals. |
| decimal | `java.math.BigDecimal` | DOUBLE type stored as a string, allowing a fixed decimal point. |
| null | `java.lang.Void` | null |
| bytes | `byte[]` | bytes. |
| date | `java.time.LocalDate` | Only the date is stored. From January 1, 0001 to December 31, 9999. |
| time | `java.time.LocalTime` | Only store time. Accuracy is 100 nanoseconds. |
| timestamp | `java.time.LocalDateTime` | Stores a unique number that is updated whenever a row is created or modified. timestamp is based on the internal clock and does not correspond to real time. There can only be one timestamp variable per table. |
