NoteOnly supported data types are included here. |
The following table identifies how SQL Anywhere or UltraLite remote data types are mapped to Microsoft SQL Server consolidated data types. For example, a column of type DATE on the remote database should be type DATETIME on the consolidated database.

DATETIME |
DATETIME |
SQL Server DATETIME values are accurate to 333.33 microseconds. The last digit of the fractional second is always rounded to one of 0, 3, or 7, so 0 and 1 round to 0; 2, 3, and 4 round to 3; 5, 6, 7, and 8 round to 7; and 9 rounds to 10. For download, SQL Anywhere keeps the original values from SQL Server, but for upload, the values may not be exactly the original values. Conflict resolution may fail. To successfully synchronize DATETIME, you can round the fractional second to 10 milliseconds. The year must be in the range 1753-9999. |
|
SMALLDATETIME |
SMALLDATETIME |
SQL Anywhere and UltraLite SMALLDATETIME is implemented as TIMESTAMP. The Adaptive Server Enterprise SMALLDATETIME is accurate to the minute. 29.998 seconds or lower are rounded down to the nearest minute; values with 29.999 seconds or higher are rounded up to the nearest minute. SQL Anywhere or UltraLite SMALLDATETIME is accurate to the microsecond. In order to successfully synchronize, SQL Anywhere or UltraLite SMALLDATETIME must be rounded to the minute. The year must be in the range 1900-2078. |
|
TIME |
DATETIME |
SQL Server TIME values are accurate to 333.33 microseconds. The last digit of the fractional second is always rounded to one of 0, 3, or 7, so 0 and 1 round to 0; 2, 3, and 4 round to 3; 5, 6, 7, and 8 round to 7; and 9 rounds to 10. For download, SQL Anywhere keeps the original values from SQL Server, but for upload, the values may not be exactly the original values. Conflict resolution may fail. To successfully synchronize TIME, you can round the fractional second to 10 milliseconds. The year must be in the range 1753-9999. |

The following table identifies how Microsoft SQL Server consolidated data types are mapped to SQL Anywhere or UltraLite remote data types. For example, a column of type TEXT on the remote database should be type LONG VARCHAR on the consolidated database.

REAL can cause problems if the consolidated and remote databases don't allow the exact same (imprecise) values. We do not test all possible values, so care must be taken. To avoid problems, do not use these types as part of a primary key. |
|
DATETIME |
TIMESTAMP or DATETIME |
The Adaptive Server Enterprise DATETIME values are accurate to 1/300 second. The last digit of the fractional second is always 0, 3, or 6. Other digits will be rounded to one of these three digits, so, 0 and 1 round to 0; 2, 3, and 4 round to 3; 5, 6, 7, and 8 round to 6; and 9 rounds to 10. For download, SQL Anywhere keeps the original values from Adaptive Server Enterprise, but for upload, the values may not be exactly the original values. If DATETIME is used for a primary key, conflict resolution may fail. In order to successfully synchronize DATETIME, you should round the fractional second to 10 milliseconds. The year must be in the range 1753-9999. |

The year must be in the range 1900-2078. |

CHAR(n) |
VARCHAR(n) |
There is no equivalence between SQL Anywhere CHAR and non-SQL Anywhere CHAR. SQL Anywhere CHAR is equivalent to VARCHAR. You should not use CHAR in a consolidated database column that is synchronized. If you must use non-SQL Anywhere CHAR, run the MobiLink server with the -b option. |

NCHAR(n) |
NVARCHAR(c) |
Not available in UltraLite. There is no equivalence between SQL Anywhere NCHAR and non-SQL Anywhere NCHAR. SQL Anywhere NCHAR is equivalent to NVARCHAR. You should not use NCHAR in a consolidated database column that is synchronized. If you must use non-SQL Anywhere NCHAR, run the MobiLink server with the -b option. |
