otBigInt

Exact numeric value with precision 19 (if signed) or 20 (if unsigned) and scale 0 (signed: –2[63] <= n <= 2[63] – 1, unsigned:0 <= n <= 2[64] – 1) (SQL_BIGINT). This maps to Int64.

otBinary

A stream of binary data (SQL_BINARY). This maps to an Array of type Byte.

otBit

Single bit binary data (SQL_BIT). This maps to Boolean.

otChar

A fixed-length character string (SQL_CHAR). This maps to String.

otDateTime

Date data in the format yyyymmddhhmmss (SQL_TYPE_TIMESTAMP). This maps to DateTime.

otDecimal

Unicode character string of fixed string length (SQL_WCHAR). This maps to String.

otNText

Unicode variable-length character data. Maximum length is data source–dependent. (SQL_WLONGVARCHAR). This maps to String.

otNVarChar

A variable-length stream of Unicode characters (SQL_WVARCHAR). This maps to String.
