SnowConvert: Sybase IQ Data Types¶

Data Types¶

Exact and approximate numerics¶

SybaseSnowflakeNotes
SybaseSnowflakeNotes
BIGINTBIGINT

​Note that BIGINT in Snowflake is an alias for NUMBER(38,0)

[See note on this conversion below.]

BITBOOLEANSybase only accepts ​1, 0, or NULL
DECIMALDECIMAL​Snowflake's DECIMAL is synonymous with NUMBER
FLOATFLOAT

​This data type behaves equally on both systems.

Precision 7-15 digits, float (1-24)

Storage 4 - 8 bytes, float (25-53)

INTINT

Note that INT in Snowflake is an alias for NUMBER(38,0)

[See note on this conversion below.]

SMALLINTSMALLINT​​This data type behaves equally
TINYINT​TINYINT

Note that TINYINT in Snowflake is an alias for NUMBER(38,0)

[See note on this conversion below.]

NUMERICNUMERIC​Snowflake's NUMERIC is synonymous with NUMBER

NOTE:

  • Each is converted to the alias in Snowflake with the same name for the conversion of integer data types (INT, SMALLINT, BIGINT, TINYINT). Each of those aliases is converted to NUMBER(38,0), a data type considerably larger than the integer datatype. Below is a comparison of the range of values that can be present in each data type:

    • Snowflake NUMBER(38,0): -99999999999999999999999999999999999999 to +99999999999999999999999999999999999999

    • Sybase TINYINT: 0 to 255

    • Sybase INT: -2^31 (-2,147,483,648) to 2^31-1 (2,147,483,647)

    • Sybase BIGINT: -2^63 (-9,223,372,036,854,775,808) to 2^63-1 (9,223,372,036,854,775,807)

    • Sybase SMALLINT: -2^15 (-32,768) to 2^15-1 (32,767)

Date and time ¶

Notes

DATE

DATE

Sybase accepts range from 0001-01-01 to 9999-12-31

DATETIME

TIMESTAMP_NTZ(3)

Snowflake’s DATETIME is an alias for TIMESTAMP_NTZ​

SMALLDATETIME

TIMESTAMP_NTZ

Snowflake’s DATETIME truncates the TIME information

i.e. 1955-12-13 12:43:10 is saved as 1955-12-13

TIME

​This data type behaves equally on both systems.

Range 00:00:00.0000000 through 23:59:59.9999999

Notes

BINARY

​BINARY

In Snowflake the maximum length is 8 MB (8,388,608 bytes) and length is always measured in terms of bytes.

VARBINARY

VARBINARY

Snowflake use this data type as a synonymous with BINARY.

Snowflake often represents each byte as 2 hexadecimal characters
