In addition, you can specify the psl_mode as a bitmask of the flags described above. Table 189-1 DBMS_SYNC_REFRESH Package Subprograms. One of the side effects of this procedure is that the tables being prepared are locked in this sense: the staging logs of the tables will be locked to prevent any DMLs from occurring and the registration of partition operations will be disabled. So, for example, something that has a promise date of 2021-11-07 00:00:00.0000000 will have a modified promise date of 2021-11-05 00:00:00.0000000 (considering Sunday as the seventh day).

In this tutorial, you have learned how to use the Oracle TRUNC() function to truncates a date value to a specified unit. This function returns the group ID of a materialized view. This procedure registers a list of materialized views for synchronous refresh. The time part will be zero as well: If you specify 'MM' or 'MONTH' unit in Oracle TRUNC, the datetime is truncated to month (day is set to 1, and time is set to 00:00:00): In SQL Server, you can convert a datetime to VARCHAR(7) using style 120 to get the YYYY-MM format, then add '-01', and convert to DATETIME or DATETIME2: If you specify 'YY' or 'YEAR' unit in Oracle TRUNC, the datetime is truncated to year (month and day are set to 1, and time is set to 00:00:00): In SQL Server, you can convert a datetime to VARCHAR(4) using style 120 to get the year, then add '-01-01', and convert to DATETIME or DATETIME2: You can also use YEAR or DATEPART function to get the year, convert it to string, add '-01-01' and then convert to DATETIME or DATETIME2: If you specify 'HH24' or 'HH' unit in Oracle TRUNC, the datetime is truncated to hour (minutes and seconds are set to 00:00): In SQL Server, you can convert a datetime to VARCHAR(13) using style 120 to get the 'YYYY-MM-DD HH24' format, add ':00:00', and convert to DATETIME or DATETIME2: If you specify 'MI' unit in Oracle TRUNC, the datetime is truncated to minute (seconds are set to zero): In SQL Server, you can convert a datetime to VARCHAR(16) using style 120 to get the 'YYYY-MM-DD HH24:MI' format, add ':00', and convert to DATETIME or DATETIME2: SQLines offers services and tools to help you migrate databases and applications. The group IDs of all the lists of tables can be retrieved with GET_ALL_GROUP_IDS. If you can recreate the table (or add columns, copy data, drop the old and rename) you can use the datatype TIMESTAMP(3). Using COMPUTATIONAL-5 or COMP-5 has the same effect, regardless whether the TRUNC compiler option is in effect. Note that the general form of this datatype is NUMBER(p,s), where p is the variable for precision and s is the variable for scale. DECFLOAT16: 0.000 000 000 000 001 x 10-383, DECFLOAT34: 0.000 000 000 000 000 000 000 000 000 000 001 x 10-6143, DECFLOAT16: 9.999 999 999 999 999 x 10+384, DECFLOAT34: 9.999 999 999 999 999 999 999 999 999 999 999 x 10+6144.
