I have format exception when i trying to add '9/30/2019 5:15:54 PM'(DD-MM-YYYY) to my database.
I'm already SET datestyle = 'ISO, DMY'. So now i can use it like:
INSERT INTO products(name, createdat) values ('test', '9/30/2019 5:15:54 PM')
I have the same SQL command in C# and PostgreSQL, but it works only in Postgre-pgAdmin(nice joke C#).
How can fix this error in C#?
Well if you insert a valid Postgres timestamp literal, it should work everywhere:
INSERT INTO products (name, createdat)
VALUES
('test', '2019-09-30 17:15:54'::timestamp);
Perhaps the setting you configured were only valid from the session originating from pgAdmin, but not with the Postgres driver which C# is using. In any case, the default Postgres timestamp literal is ISO compliant (your version is not), which is always a good thing.
How can I insert Arabic characters into a SQL Server database? I tried to insert Arabic data into a table and the Arabic characters in the insert script were inserted as '??????' in the table.
I tried to directly paste the data into the table through SQL Server Management Studio and the Arabic characters was successfully and accurately inserted.
I looked around for resolutions for this problems and some threads suggested changing the datatype to nvarchar instead of varchar. I tried this as well but without any luck.
How can we insert Arabic characters into SQL Server database?
For the field to be able to store unicode characters, you have to use the type nvarchar (or other similar like ntext, nchar).
To insert the unicode characters in the database you have to send the text as unicode by using a parameter type like nvarchar / SqlDbType.NVarChar.
(For completeness: if you are creating SQL dynamically (against common advice), you put an N before a string literal to make it unicode. For example: insert into table (name) values (N'Pavan').)
Guess the solation is first turn on the field to ntext then write N with the value. For example
insert into eng(Name) values(N'حسن')
If you are trying to load data directly into the database like me, I found a great way to do so by creating a table using Excel and then export as CSV. Then I used the database browser SQLite to import the data correctly into the SQL database. You can then adjust the table properties if needed. Hope this would help.
I am using SQL Server 2008, Visual Web Developer 2012 and .net 4.0. I created a table in SQL Server and added some columns to it. I gave some columns the datatype nchar(10).
Now my problem is that when I insert string of less than 10 characters as a value of the column type nchar(10) and when I fetched the value it inserts blank spaces to complete the 10 character string.
Means if I insert "a" into column of type nchar(10),
then when I fetch the value again I get back: "a "
How can I resolve this issue ?
You can do like this to trim the whitespaces:
SELECT RTRIM(CAST(col As NVARCHAR(10))) FROM test
Check out SQLFIDDLE
define the string as nvarchar(10) it will work fine
If you don't want to change data type, then you will need to TRIM the space from the output
SELECT
RTRIM("a ") AS ColumnName
FROM MyTable
But this means every time you have to do this every place you are using the column. It is better to user VARCHAR(10) or NVARCHAR(20) where VAR... means variable length. So if your string is not up to 10 characters, spaces are not added
Final SQL
SELECT
RTRIM(ColumnName) AS ColumnName
FROM myTable
I'm using the C# .NET Mysql Connector, and when running this query:
INSERT INTO convos (`userid`,`time`,`from`,`content`,`read`,`deleted`, `ip`, `source`, `charname`, `to`) VALUES ('3', '1347396787', 'Chára', '........', '0', '0', '0.0.0.0:0000', 'C', 'óóóíííí', 'óóóíííí');
I get the following error:
Incorrect string value: '\xE1ra' for column 'from' at row 1
I understand my encoding, everything was configured for utf8, utf8_general_ci. Database, table and columns are configured for utf8. The data is sent from the client in utf8.
If i use a 3rd party tool like, Workbench to insert the query or use the mysql command line it works fine. I don't know if there is a bug with the connector or i need to be doing something else with the values before insert?
Any idea?
Thanks
Is there any in mysql to covert to the correct type?
I believe you need to alter the column's char set:
use below code for those columns which is using UTF-8.
ALTER TABLE database.table MODIFY COLUMN col VARCHAR(255)
CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL;
Unicode string prefix with N
First see your table convos and make sure columns data types is either one of nchar, nvarchar and You must precede all Unicode strings with a prefix N when you deal with Unicode string constants in SQL Server
Tyr:
insertQuery = "INSERT INTO convos (`userid`,`time`,`from`,`content`,`read`,`deleted`, `ip`, `source`, `charname`, `to`) VALUES
(N'3', N'1347396787', N'Chára', N'........', N'0', N'0', N'0.0.0.0:0000', N'C', N'óóóíííí', N'óóóíííí')";
I figured this out, its taken a while but it seems i was setting the charset too often. The database, tables, columns are all in UTF8. When i made a connection i had "CHARSET=UTF8" in the connection string. I was also running "SET NAMES 'utf8' COLLATE 'utf8_general_ci'" everytime i made a connection. I dropped the CHARSET=UTF8 and "SET NAMES 'utf8' COLLATE 'utf8_general_ci'" and its all working now.
Update it
INSERT INTO convos (`userid`,`time`,`from`,`content`,`read`,`deleted`, `ip`, `source`, `charname`, `to`) VALUES ('3', '1347396787', 'Chara', '........', '0', '0', '0.0.0.0:0000', 'C', 'óóóíííí', 'óóóíííí');
I think for "chara"in your 3rd value gives it
For someone who has tried all the suggestions, and nothing has worked (like myself), it is worth checking what MySQL types are your fields mapped to in C#. My text fields were automatically mapped as MySqlDbType.Blob and that was causing the error. I changed the type to MySqlDbType.Text, and I don't see the error any more.
Here is my original response to a similar thread:

config mysql like below. it will solve the unicode error when insert into mysql from java or C#

I want to retrieve a table on a SQL Server database that is located on another server
and I want to store the data retrieved into my own SQL Server database.
How do I can do that?
Thanks so much
one of the easiest and best method i found in this article this might be resolve your issue easily
SQL SERVER – 2008 – Copy Database With Data – Generate T-SQL For Inserting Data From One Table to Another Table
One of the fastest method if you have a lot of data is a tool called bcp.
It allows you to export and import data to a file. So you can export from the source database and then import to the target. It is very fast.
If your destination is a SQL 2008 database and you're set on using C# to connect to the source and get the data you could use a Table parameter. A DataTable in .NET is directly mappable to a User Defined Table type in SQL Server.
Here is a SO thread about it:
How to pass User Defined Table Type as Stored Procedured parameter in C#
Define your custom table type in your destination database
create type MyCustomTable as Table
(
Field1 int,
Field2 varchar(50),
Field3 decimal(18,0)
)
The concept would be to read all of the data from the source in to a data table. Then you would use a SqlParameter to execute a stored procedure or possibly text query on your destination server. By using a stored procedure that accepts a table parameter you could do the following:
CREATE PROCEDURE dbo.BulkCopyData
(
#SourceData MyCustomTable readonly --readonly has to be there, Table params have to be readonly as parameters
) AS
BEGIN
INSERT INTO dbo.DestinationTable
(
Field1,
Field2,
Field3
--more fields
)
SELECT Field1,Field2,Field3 FROM #SourceData
END
And in C# when you go to execute the command:
DataTable dt = new DataTable(); //Go get the data from your source here
SqlConnection conn = new SqlConnection("....");
conn.Open();
SqlCommand cmd = new SqlCommand("dbo.BulkCopyData",conn)
cmd.Parameters.Add( new SqlParameter("SourceData", SqlDbType.Structured){ TypeName = "dbo.MyCustomTable ", Value = dt});
cmd.Parameters[0].
cmd.ExecuteNonQuery();
You can use also openrowset function on SQL and call/query the remote server using your SQL code. This feature is not enabled by defauld (you must use the SP_CONFIGURE stored procedure and enable the remote queries to use this functionality). Here is a link with some examples.

When you need to know how to set up the configuration just let me know ;)
Connect to your DB using SQL Server management Studio
Go to Server Objects ->Add a new Linked Server
then you can use the other table as select * from LinkedServerName.DBName.dbo.TableName
