Semicolon-delimited → SQL reference

What is a semicolon-delimited file?

A semicolon-delimited file is a plain-text file where each line is one record and a semicolon ; separates the fields. It is the usual CSV variant in locales where the decimal separator is a comma, so a comma inside a number would otherwise be ambiguous.

Name;Age;City
Alice;30;New York
Bob;41;San Francisco

To open it in Excel: Data → From Text/CSV, then set the delimiter to ;.

Type mapping

Value kind	in Semicolon-delimited	in SQL
Int	`1234`	`INT`
Bigint	`9007199254740993`	`BIGINT`
Decimal	`1234.56`	`DECIMAL(p,s)`
Float	`1.234e+10`	`DOUBLE PRECISION`
Text	`quoted only when it contains a semicolon or a quote`	`VARCHAR(n)`
Long text	`must be quoted; line breaks inside force multi-line records`	`TEXT / CLOB`
Date	`2026-09-18`	`DATE`
Datetime	`2026-09-18 14:30:00`	`TIMESTAMP`
Binary	`not representable - base64 or hex string`	`BLOB / BYTEA`
Boolean	`TRUE / FALSE, or 1 / 0 depending on the writer`	`BOOLEAN / SMALLINT`
JSON	`the whole JSON value quoted, with internal quotes doubled`	`JSON / TEXT`

dates	`Dates often use D/M/Y or D.M.Y in European exports`	`Depends on the dialect: DATE literals, TO_DATE(), or plain ...`
binary	`Not supported`	`Dialect-specific: X-quoted literal, 0x hex, or decode()`
separator	`Semicolon ";"`	`Statement terminators (;)`
