Is there some way to make postgres understand that the VALUES expression has the same type as a table row, i.e. 4 Answers Sorted by: 21 You can convert it to a timestamp with this code: SELECT currentdate::timestamp It will directly assign the time 00:00:00 to currentdate. This can be fixed by explicitly casting in the values: INSERT INTO exampleįROM (VALUES ('d853b5a8-d453-11e7-9296-cec278b6b50a'::uuid, NULL::numeric)) as data(a,b) īut that's messy and a maintenance burden. The following statement illustrates how to declare a column with the TIME data type: columnname TIME (precision) Code language: SQL (Structured Query Language) (sql) A time value may have a precision up to 6 digits. We can perform various cast operations in PostgreSQL for converting one. We have hours, minutes, and seconds that include a fractional value. Introduction Cast is a technique in PostgreSQL with which we can convert a value of one datatype into another. Above, we can see that time is represented in the 24h format. Aside from the date column, there are a few notable types that we should mention. The target data type is the data type to which the expression will get converted. PostgreSQL provides the TIME data type that allows you to store the time of day values. We use the double colons to cast the return value of the NOW function to the date type. => ERROR: column "a" is of type uuid but expression is of type text How does the CAST Operator work in PostgreSQL The cast operator converts one data type to another, where the table column or an expression’s data type is decided to be. Looks to me like any of these should work: Cast ('Orders'.'OrderDate' as Date), Date ('Orders'.'OrderDate'), 'Orders'.'OrderDate'::Date, but they all give the error cannot change data type of view column 'OrderDate' from timestamp without time zone to date Postgres 11 pgAdmin 4. to qualify with a WHERE clause), but this can get postgresql confused about the column types.Įxample: CREATE TABLE example (a uuid primary key, b numeric) įROM (VALUES ('d853b5a8-d453-11e7-9296-cec278b6b50a', NULL)) as data(a,b) 33 4 maybe you're using UTC-5 time zone Kristian at 8:42 Add a comment 1 Answer Sorted by: 0 If you just want to convert the string to a Postgres timestamp then: select ''::timestamptz 22:04:11 PDT The output will depend on the DateStyle setting. 1 In a view, I'm casting a timestamp without timezone to date. It's often desirable to INSERT from a SELECT expression (e.g.
