Note that because this method is not available in the generic IDbConnection interface, you must cast the object as SnowflakeDbConnection before calling the method. For example: CancellationTokenSource cancellationTokenSource = new CancellationTokenSource(); // Close the connection ((SnowflakeDbConnec...
SELECTCAST(contentASMAP<STRING,STRING>)AScontentFROMevent 报错: cannot resolve `content`' due to data type mismatch: cannot cast string to map<string,string>。哦,原来我的数据里,有的value是数值类型,不全是STRING类型,导致错误。而Spark中并没有一种类型能直接同时代表 INT 和 STRING。 换个思路,如果...

|SNOW-33227| Added support for new session parameter, JDBC_TREAT_DECIMAL_AS_INT, which, if set to TRUE (default value) instructs the driver to treat a column whose scale is zero as BIGINT instead of DECIMAL. |SNOW-33042| Added support to driver for PUT/GET over encrypted staged files ...
When passed a VARCHAR expression, this function implicitly casts the input to floating point values. If the cast cannot be performed, an error is returned. When this function is called as a window function with an OVER clause that contains an ORDER BY clause: ...
The VARIANT and OBJECT columns will also be output as JSON strings by default, forcing us to cast these when inserting them into ClickHouse. Importing to ClickHouse Once staged in intermediary object storage, ClickHouse functions such as the s3 table function can be used to insert the data ...
If the cast cannot be performed, an error is returned. When this function is called as a window function with an OVER clause that contains an ORDER BY clause: A window frame is required. If no window frame is specified explicitly, the following implied window frame is used: RANGE BETWEEN ...
