Insert an array to sql

No, not as an array of values intended for different rows - SQL doesn't have any concept of arrays, so it won't understand them. It is possible (though a PITA to do this via a string made up of comma delimited values, but that is best done as a stored procedure, rather than by an INSERT statement.
 
If it is an array of bytes that you want into a varBinary field on the other hand, then yes - pass the array content to SQL as a parameter value and it will work fine. (Exactly how you do that depends on your coding language)

This is what I do, regularly and with increasing frequency:

CREATE TABLE [solutionfour].[test].[theanswer](
	[text] [nvarchar](MAX)
	)
				
CREATE TABLE [solutionfour].[test].[theanswerIdx](
	[idx][int]IDENTITY(1,1) NOT NULL,
		[text] [nvarchar](MAX)
		)
 
BULK INSERT [solutionfour].[test].[theanswer] 
	FROM 'C:\arrayMine.txt'							
		WITH (
			--CODEPAGE = 'RAW'
			CODEPAGE = 'ACP' 
			)
 
INSERT INTO [solutionfour].[test].[theanswerIdx]
	SELECT [text] FROM [solutionfour].[test].[theanswer]
 

Then go to work. See help for TSQL string commands and info on casting and converting as needed ...
 
Any further questions?

The relational model itself is dealing with multi-value attributes. Most of the relational database management systems are targeting the 3NF[^]. But not all, Firebird for example is supporting array data types[^].
SQL Server is not supporting such data type, but if you really need it, you can use several tools to emulate this feature. This is a really good collection of them: http://www.sommarskog.se/arrays-in-sql-2005.html[^]
I, for myself would prefer the XML approach.

for that you have to create query like that:
assume you have ArrayList arrList having 5 employeename so you can create query like

 string strQuery = "Insert Into YourTableName (YourColumnName) values (";
 for(int i=0; i<arrlist.count;i++)>
 {
   strQuery += arrList[i];
   if(i<arrlist.count-1)>
       strQuery += ",";
 }
 
 now use this query so that you can insert multiple value in single insert statement.
