Detailed Description

Class used to access individual fields of database query result.

Guideline on field type matching:

MySQL type method to use
TINYINT Get<bool>, Get<int8>, Get<uint8>
SMALLINT Get<int16>, Get<uint16>
MEDIUMINT, INT Get<int32>, Get<uint32>
BIGINT Get<int64>, Get<uint64>
FLOAT Get<float>
DOUBLE, DECIMAL Get<double>
CHAR, VARCHAR, Get<std::string>, Get<std::string_view>
TINYTEXT, MEDIUMTEXT, Get<std::string>, Get<std::string_view>
TEXT, LONGTEXT Get<std::string>, Get<std::string_view>
TINYBLOB, MEDIUMBLOB, Get<Binary>, Get<std::string>
BLOB, LONGBLOB Get<Binary>, Get<std::string>
BINARY, VARBINARY Get<Binary>

Return types of aggregate functions:

Function Type
MIN, MAX Same as the field
SUM, AVG DECIMAL
COUNT BIGINT
