Connection string with some databases
Mysql
jdbc:mysql://{host-ip}:{porta}/{nome-database}
Progress DB
jdbc:datadirect:openedge://{host-ip}:{porta};databaseName={nome-database};
MSsql - SQL Server
jdbc:sqlserver://{host-ip}:{porta};databaseName={nome-database}
Oracle
jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = {host-ip})(PORT = {porta})))(CONNECT_DATA =(SERVICE_NAME = {nome-database})))
PostGreSQL
jdbc:postgresql://{host-ip}:{porta}/{nome-database}
Sybase
This string is different from the others, because the connection properties go together with the string after the question mark:
jdbc:sybase:Tds:{host-ip}:{porta}/{nome-database}?DYNAMIC_PREPARE={dynamic-prepare}&APPLICATIONNAME={applcation-name}__________________________________________________________________
SQL Server - Tables Description
This is an example of how to list the columns of the table in SQL Server by using "select":
desc SQL SERVER
SELECT column_name AS [name],
IS_NULLABLE AS [null?],
DATA_TYPE + COALESCE('(' + CASE WHEN CHARACTER_MAXIMUM_LENGTH = -1
THEN 'Max'
ELSE CAST(CHARACTER_MAXIMUM_LENGTH AS VARCHAR(5))
END + ')', '') AS [type]
FROM INFORMATION_SCHEMA.Columns
WHERE table_name = 'TB_CLIENTES'

SQL Server - Tips to use pagination
DECLARE @PageNumber AS INT, @RowspPage AS INT
SET @PageNumber = 2
SET @RowspPage = 5
SELECT * FROM (
SELECT ROW_NUMBER() OVER(ORDER BY ID_EXAMPLE) AS NUMBER,
ID_EXAMPLE, NM_EXAMPLE, DT_CREATE FROM TB_EXAMPLE
) AS TBL
WHERE NUMBER BETWEEN ((@PageNumber - 1) * @RowspPage + 1) AND (@PageNumber * @RowspPage)
ORDER BY ID_EXAMPLE

Timeout Oracle Configuration
The information below must be sent in the CUSTOM CONNECTION PROPERTIES field in DB Connector so there's a greater control of its connection timeout with the database:
{
"oracle.jdbc.ReadTimeout": "60000",
"oracle.net.CONNECT_TIMEOUT": "10000"
}
Timeout SQL Server Configuration
{
"queryTimeout": 10,
"cancelQueryTimeout": 10
}
