当您虚拟化Snowflake数据源中的表时,Data Virtualization会将类型为 STRING , TEXT 和 VARCHAR 的数据转换为类型 CLOB ,而不是类型 VARCHAR (当它们超过最大字符串长度时)。 症状 当您虚拟化包含数据类型 STRING , TEXT 和 VARCHAR (超出MaxStringSize参数的缺省最大字符
當您虛擬化的Snowflake表格包含的資料類型 STRING、TEXT 及 VARCHAR 超過MaxStringSize參數的預設字串長度上限 32 K 時,直欄的資料類型會轉換為 CLOB。 Snowflake會針對 STRING、TEXT 和 VARCHAR 類型指定長度上限 16,777,216 (如果長度上限不是使用者定義的)。 因此,Data Virtua...

It was a classic case of human error while updating a stored procedure and we are storing the value of another VARCHAR variable into a char(1) field. Since both values are quite similar, we didn't realize until we checked every single field. The biggest challenge with this p...
When you virtualize tables in a Snowflake data source, Data Virtualization converts data with types STRING, TEXT, and VARCHAR to type CLOB instead of type VARCHAR when they exceed the maximum string length.
