I use Laravel 5.6.x framework, i have a connection on a Mysql database of which one of the tables contains a Time(6) field type.
sample value : '00:01:02.154120'
I want my model to receive the value with same precision but i always get a truncated value corresponding to 'H:i:s' format even i cast my column to datetime or string.
I created my table from migration and i saw Blueprint support well precision option for time type since version 5.5. So i guess there is a way to retrieve the whole value ?
How can i achieve this ?
This is a known problem: https://github.com/laravel/framework/issues/24214
It's caused by a bug in PHP that will be fixed in 7.3: https://github.com/php/php-src/pull/3257

There are similar questions, but I am beginning to think mine is related to Spark jdbc APIs since both components seem to be working correctly on their own. I am using Spark 2.4 (which has ms support for timestamps) and have a MySQL 5.7.x version that supports fractional seconds.
I created a simple Dataset, with a TimestampType column, and when I show() it, here is what I get:
+-----------------------+
|my_timestamp |
+-----------------------+
|2021-02-06 12:11:45.335|
+-----------------------+
When I write this to MySQL (using dataset.write()), it creates the table automatically, with SQL TIMESTAMP type for the column, and the milliseconds part is lost upon insert.
For a second test, I created the table manually and defined the colon as TIMESTAMP(3). When I manually insert timestamps with ms part to it, everything works correctly. But when I write using Spark jdbc APIs, once again the ms part is truncated and it becomes 2021-02-06 12:11:45.0.
The only workaround that comes to mind is to keep the column as a long/BIGINT and convert it to DATETIME/TIMESTAMP when querying.
Am I doing something wrong here?
Well, StringType to the rescue. Apparently if I keep the Spark column as String with a value formatted the way MySQL expects, e.g. "2020-11-20 23:06:41.745", I can insert to a MySQL TIMESTAMP(3) column without any truncation or other problems.
This feels more like a workaround, so I still want to learn if there is a way to do this correctly.
I have a requirement where I have to load Informatica SESSSTARTTIME(datetime) to SQL server timestamp. When I am trying to connect datetime to timestamp I am getting error incompatible data type.
Any suggestions how this can be achieved?
Thanks
I had a similar issue in the past, where the date column was not getting loaded because of the difference in precision of date/time used by Informatica and SQL server. You can try this workaround: Change the data type in the target definition (not in SQL Server table, only in Informatica Target definition) to String, then Informatica will pass the date/time value in quotes when firing the insert query, which SQL server can convert to date/time automatically.
in the mapping try to create output port in expression as sessionstarttime (which is a inbuilt variable) and pass it to target
hope this will help to get desire output
in session there is config tab where you can change the format for date and time
MS SQL Server timestamp datatype has nothing to do with time. It's an autogenerated number and you cannot load it.

quote:
"Is a data type that exposes automatically generated, unique binary numbers within a database. timestamp is generally used as a mechanism for version-stamping table rows. The storage size is 8 bytes. The timestamp data type is just an incrementing number and does not preserve a date or a time. To record a date or time, use a datetime data type."
MySQL Workbench doesn't allow me to use BLOB() and DATETIME() data types. Im getting this error.
The problem is your data types are incomplete. BLOB and DATETIME (as well as a few other types) allow to specify precisions within parentheses. MySQL Workbench adds empty ones for you, but you have to fill them with a good value. Alternatively, you can just remove them to use the default precision.
Instead of BLOB() and DATETIME() use BLOB and DATETIME respectively
I am using MySql .net connector 6.3.6 and Visual Studio 2008 sp1.
One of the table in the database has a timestamp column.
When I generate Entity mappings (.edmx file), the timestamp column is getting mapped to DateTimeOffset data type.
And when I hit a Linq query on this table, I always get Null value for this column (this column is nullable) even though there are valid non-null values in the table for this column.
If I try to update the mapping to a datetime datatype, visual studio throws error.
I tried to google for possible solutions, and many places it was mentioned that MySql timestamp column should map to .net datetime datatype by default.
I am not sure what the problem is?
Thanks.
I recommend you to try dotConnect for MySQL. It generates DateTime properties for the corresponding Timestamp columns.
You can download a Trial version here, the only limitation of this version is 30-day trial period.
Update. You can try editing the .edmx file using an XML editor. Set the type of the CSDL property to DateTime, and if this causes any validation issues you can try setting the type of the SSDL property to "datetime" as well.
Hi when saving to a model, my created and modified fields aren't automatically populated by CakePHP. It was automatically populated when I was using MySQL but now it isn't. I'm not using NOW() back when I was still using MySQL. Why is it? Also when a field's value is not set 'NULL' (with quotes) is inserted causing errors because SQL Server says I can't insert a string to a field of type smallint/date etc. How do I fix this?
Thanks in advance!
I would set NULL as a keyword rather than quoting it, which I imagine is why your database thinks that it's a string.
Have you double checked the schema of the database to ensure that the created and modified fields are still DATETIME fields.
Also you say "SQL Server", and mention MySQL, so I assume that you are now using MSSQL?
