Funções e utilidades para banco de dados

Aprenda sobre funções gerais e usos da Digibee Integration Platform ao criar pipelines de integração.

String de conexão de alguns bancos de dados

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

Essa string é diferente das outras, porque as propriedades da conexão vão junto da string após o ponto de interrogação:

jdbc:sybase:Tds:{host-ip}:{porta}/{nome-database}?DYNAMIC_PREPARE={dynamic-prepare}&APPLICATIONNAME={applcation-name}

SQL Server - Descrição de Tabelas Este é um exemplo de como listar as colunas da tabela no SQL Server através de 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'

My SQL - Descrição de Tabelas

DESCRIBE tb_nome_tabela;
SHOW COLUMNS FROM tb_nome_tabela LIKE ‘I%’;

Oracle - Função equivalente ao IN

{"ufs":",SP,PR,"}
SELECT c.IDCIDADES as  id_cidade, c.UF, c.nome, ','||c.UF||',' 
as UF FROM CIDADES c  where  instr({{ message.ufs }}, ','||c.UF||',')  > 0

Oracle - Conversão de timestamp (number) para date

SELECT TO_CHAR( TO_DATE('19700101','yyyymmdd') + 
(1551129634776/1000/24/60/60), 'YYYYMMDD HH24:MI:SS')thedate 
FROM dual

Oracle - Selecionar nome de colunas de uma tabela

SELECT table_name, column_name, data_type, data_length
FROM USER_TAB_COLUMNS
WHERE table_name = 'MYTABLE'

Oracle - Em caso de erros de constraint, utilizar a query para identificar os campos e tabelas relacionados.

SELECT   uc.constraint_name||CHR(10)
   ||      '('||ucc1.TABLE_NAME||'.'||ucc1.column_name||')' constraint_source
   ,       'REFERENCES'||CHR(10)
   ||      '('||ucc2.TABLE_NAME||'.'||ucc2.column_name||')' references_column
FROM all_constraints uc ,
  all_cons_columns ucc1 ,
  all_cons_columns ucc2
WHERE uc.constraint_name = ucc1.constraint_name
AND uc.r_constraint_name = ucc2.constraint_name
AND ucc1.POSITION        = ucc2.POSITION -- Correction for multiple column primary keys.
AND uc.constraint_type   = 'R'
AND uc.constraint_name   = 'FK_3844_60806'
ORDER BY ucc1.TABLE_NAME ,
  uc.constraint_name

SQL Server - Dicas de utilizar a paginação

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

Configuração Timeout Oracle A informação abaixo deve ser passada no campo CUSTOM CONNECTION PROPERTIES no componente DB v2 para que haja maior controle do timeout da sua conexão com o banco de dados:

Postgres

{
  "loginTimeout": "50",
  "connectTimeout": "50",
  "socketTimeout": "50",
  "cancelSignalTimeout": "50"
}

SQLServer

{
    "cancelQueryTimeout": 5,
    "queryTimeout": 15,
    "lockTimeout": 15000,
    "socketTimeout": 15000
}

Oracle

{
    "oracle.jdbc.ReadTimeout": 15000,
    "oracle.net.CONNECT_TIMEOUT": 15000
}

MySQL (via URL)

jdbc:mysql://{{mysql-dbo-ip}}/dbo?serverTimezone=UTC&connectTimeout=400000
