Magic squishy balls are a popular toy that has gained popularity in recent years. These balls are made from a special material that allows them to be stretched, squished, and molded into different shapes. They come in various sizes, colors, and textures, making them appealing to both children and adults. One of the main features of magic squishy balls is their ability to bounce back to their original shape after being squished. This gives users a sense of satisfaction and stress relief as they can squeeze the ball as hard as they want without permanently damaging it. Magic squishy balls are often used as sensory toys for individuals with sensory processing disorders or autism.
Após vários testes, conclui que não é recomendado utilizar o parâmetro TABLE_EXISTS_ACTION=APPEND, devido às restrições de integridade que são impostas pela regra de negócio do cliente. Para este parâmetro trabalhar corretamente, observei que é preciso checar as dependências das tabelas envolvidas, caso contrário, vai ocorrer o erro ORA-0001: unique constraint violated.

Magic squishy balls are often used as sensory toys for individuals with sensory processing disorders or autism. The soft texture and malleable nature of the balls can provide comfort and help with sensory regulation. Moreover, these squishy balls are also known for their therapeutic benefits.
O parâmetro TABLE_EXISTS_ACTION do impdp: Como usá-lo para importar e atualizar tabelas no banco de dados ARTIGO EXCLUSIVO
No artigo de hoje vou falar sobre o parâmetro TABLE_EXISTS_ACTION do impdp, também vou criar um exemplo prático para que vocês entendam melhor o conceito.
Este parâmetro deve ser usado em conjunto com o parâmetro TABLES, que especifica as tabelas que serão importadas. Este parâmetro define qual ação tomará o Data Pump quando encontrar uma tabela que já existe no banco de dados.
O parâmetro pode ter os seguintes valores:
- SKIP – nenhuma ação é tomada, ignora a(s) tabela(s) existente(s).
- APPEND – novas linhas serão acrescentadas a tabela existente.
- TRUNCATE – apaga as linhas da(s) tabela(s), em seguida, efetua a carga dos dados.
- REPLACE – substitui a(s) tabela(s) existente(s); implicitamente, é executado os comandos DROP TABLE e CREATE TABLE, depois é feito a carga dos dados.
PASSO A PASSO
Passo 1 – Criando o HREX, importando tabelas do HR para o HREX:

COMMIT;Passo 4 – Importando tabela DEPARTMENTS:
Comparando a tabela dos esquemas HR e HREX, nota-se a ausência do departamento 280 na tabela HREX.DEPARTMENTS.
Para que as tabelas fiquem iguais, vamos substituir a tabela do esquema HREX pela tabela do HR.
Passo 5 – Importando tabela APPLICANTS:
Neste passo, vamos importar a tabela APPLICANTS do esquema HR para o HREX, através do “comando” TRUNCATE. Quando utilizamos esta opção, o Data Pump apaga todas as linhas da tabela e “popula” ela com os dados do ambiente de origem.
Passo 6 – Importando tabelas EMPLOYEES, APPLICANTS, APPLICANTS2:
Vamos importar as tabelas EMPLOYEES, APPLICANTS e APPLICANTS2 do esquema HR para o esquema HREX. As tabelas que já existem no esquema HREX não serão importadas, as outras tabelas sim. Para exemplificar, criei a tabela HR.APPLICANTS2.
Conclusão
Após vários testes, conclui que não é recomendado utilizar o parâmetro TABLE_EXISTS_ACTION=APPEND, devido às restrições de integridade que são impostas pela regra de negócio do cliente. Para este parâmetro trabalhar corretamente, observei que é preciso checar as dependências das tabelas envolvidas, caso contrário, vai ocorrer o erro ORA-0001: unique constraint violated.

Reviews for "The Geometric Wonders of Magic Squishy Balls"
1. Jennifer - 2 stars - I was really disappointed with the "Magic squishy bals". The product did not live up to its claims at all. The squishy bals were not as squishy as they were advertised to be, and they lost their shape easily. The texture was also unpleasant, it felt sticky and slimy. Overall, I did not enjoy playing with them and would not recommend them.
2. Mark - 1 star - I regret buying the "Magic squishy bals". They were a complete waste of money. The product was poorly made and fell apart after just a few uses. The bals also had a strong chemical smell that was very off-putting. I expected a fun and entertaining toy, but all I got was disappointment. Save your money and stay away from this product.
3. Sarah - 2 stars - The "Magic squishy bals" were not as magical as they claimed to be. The packaging promised that they would change colors with heat, but that rarely happened. Even when I tried to warm them up with my hands, there was minimal color change. The bals also left stains on my hands and clothes, which was frustrating. I would not recommend this product as it did not deliver on its promises.
4. Michael - 1 star - I had a terrible experience with the "Magic squishy bals". The product arrived damaged, with some bals already torn and leaking some weird liquid. I reached out to customer service for a refund or replacement, but they were unresponsive. This was a huge disappointment and I would advise against purchasing these squishy balls.
5. Emily - 2 stars - I bought the "Magic squishy bals" for my kids, and they were not impressed. The bals felt sticky and had a weird smell, making them unappealing to play with. The color-changing aspect was also disappointing, as it rarely worked. My kids lost interest in them quickly and I feel like I wasted my money on a subpar product.
