Database Mashable Support and Limitations

Mashables : Types of Mashable Information Sources : Database Mashables : Database Mashable Support and Limitations

Presto supports databases with a JDBC 2.1 compliant driver. Some databases support valid names that Presto does not support. See Database Characters and Names That Are Not Supported for details.

Database mashables can use any combination of tables, views or stored procedures defined in one schema or catalog within one datasource. Presto does not support distributed transactions.

Presto does not support columns with an image datatype.

Currently, Presto handles packages for stored procedures and REF CURSOR types in Oracle databases only, with the following limitations:

Both weakly- and strongly-typed REF CURSORs are supported.

REF CURSORs are supported only in OUT parameters for stored procedures or as the return type for functions.

REF CURSORs are not supported as IN or INOUT parameters.

Nested REF CURSORs are not supported.

See also Valid Date Formats for Presto Mashables and Mashups for the specific date formats you may use in input parameters to database mashable operations.

EEEE, MMMM DD, YYYY	MMMM DD, YYYY	MMM DD, YYYY
Where EEEE is the day of the week, MMMM is the full month name and MMM is a three-character abbreviation of the month.
MM/DD/YY hh:mm:ss a z	Or these formats where time uses a twelve-hour clock (1-12), a is AM or PM and z indicates the time zone.
MM/DD/YY hh:mm:ss a
MM/DD/YY hh:mm a
MM/DD/YY
And finally, these formats where time uses a 24-hour clock
YYYY/MM/DD hh:mm:ss.sss	YYYY-MM-DD hh:mm:ss.sss	YYYY.MM.DD hh:mm:ss.sss
YYYY/MM/DD hh:mm:ss	YYYY-MM-DD hh:mm:ss	YYYY.MM.DD hh:mm:ss
YYYY/MM/DD hh:mm	YYYY-MM-DD hh:mm	YYYY.MM.DD hh:mm
YYYY/MM/DD	YYYY-MM-DD	YYYY.MM.DD
