Type mapping

Value kind	in MySQL	in CSV
Int	INT	1234
Bigint	BIGINT	9007199254740993
Decimal	DECIMAL(p,s)	1234.56
Float	DOUBLE	1.234e+10
Text	VARCHAR(n)	quoted only when it contains a comma or a quote
Long text	LONGTEXT	must be quoted; line breaks inside force multi-line records

Datetime	DATETIME	2026-09-18 14:30:00

Dialect differences

MySQL is a database server and CSV is a file format, so the gap is wider than a dialect difference - the rows below are where values and structure stop lining up.

Property	in MySQL	in CSV
port	3306	—
identifiers	`backtick`	Double quotes; a literal quote is doubled ("" )
row limit	LIMIT n	—
dates	DATETIME, TIMESTAMP, DATE, TIME	Conventional text: 2026-09-18 or 2026-09-18 14:30:00
long text	TINYTEXT / TEXT / MEDIUMTEXT / LONGTEXT	—
binary	BLOB / TINYBLOB / LONGBLOB	Not supported
separator	—	Comma ","
encoding	—	No declaration - UTF-8 works only with a BOM
typing	—	None - every field is text
shape	Tables of rows and columns	Flat table, optional header row
ceiling	—	No formal limit; row count bounded by memory

Command line

Side	Command
MySQL	mysqldump, or mysql -e "SELECT ..." > out.csv
