When you export the database, just export that particular schema using pg_dump with -schema=schemaName In all your table names, but the using the default means you can move data between schema's and one simple SQL command switches between them, great for upgrading production data, etc It is not absolutely necessary to set the search path, you could user the reference to the table as schema.table data.mytable I then set that schema to be the default by using the alter database "mydb" set search_path=data,public What I do is that I create a schema in the database, say "data" create schema data The reason is that when you export the database, you get all the PostGis objects, functions, tables, etc which are installed there. It is generally a good practice to use a different schema from the default public schema. csv", fileName)) Response.Charset = " " Response.ContentType = " application/vnd.xls" // GET Data From Database SqlConnection cn = new SqlConnection(dataSrc.ConnectionString) string query = ( " \r\n", " ").Replace( " \t", " ") SqlCommand cmd = new SqlCommand(query, cn) cmd.CommandTimeout = 999999 cmd.CommandType = CommandType.Have a look at Postgres Schemas (which are very easy to use)
EXPORT DATA FIELD POSTVIEW CODE
We have written this code at the Click event of "btnExportFromDataGrid".Ĭollapse Copy Code protected void btnExportFromDatagrid_Click( object sender, EventArgs e).
Our next objective is to export this data from datagrid to excel.
EXPORT DATA FIELD POSTVIEW FULL
Now we have a grid full of data from the database. Beside of this I have taken two buttons named "btnExportFromDatagrid" and "btnExportFromDataset". When the asp.net page would be rendered the "grdStudentMarks" would be populated by the data of "student" table of "UniversityManager" Database. When bound to a data source, the DataGrid and GridView controls each display a row from a DataSource as a row in an output table.Ĭollapse Copy Code No Data Found Like the DataGrid control, the GridView control was designed to display data in an HTML table. The GridView control is the successor to the DataGrid control. For showing this data to a grid I am using asp.net GridView control. SqlDataSource can be used as a data source which can fetch data from database and it can be bound to asp.net control. I am using a asp.net SqlDataSource control to pull the data from database. The structure of the table is as follows: Let us assume that we have a database named "UniversityManager" and it has a table named "Student".
I am using a simple form of database table to avoid unnecessary overhead. This sample is performed by using ASP.NET 2.0, C# AND SQL Server 2005.
