HSQLDB importing a text table file into a traditional table

问题

i have two the same table structure

cache table (normaltable)
text table (textfiletable)

i want to copy data from table [2] into table [1]

i'm using this insert syntax

INSERT INTO normaltable ("COL1", "COL2", "COL3")
SELECT COL1, COL2, COL3
FROM textfiletable;

i get this error

data exception:string data, right truncation/Error code: -3401/state: 22001

when using another insert syntax

SELECT COL1, COL2, COL3
INTO normaltable
FROM textfiletable;

i get this error

unexpected token : INTO required: FROM:line:2/error code: -5581/state:42581

can anybody explain?

im update the detail of my script for you to refer:

drop table pis_mdc;
drop table normaltable;
drop table textfiletable;

The unexpected token error is a syntax error. It means this syntax is not supported in version 2.x.

The data exception error means some string stored in the TEXT table is too large to insert into the field in the CACHED table. Try a query such as:

SELECT MAX(CHAR_LENGTH(UD_MDC_CODE)), MAX(CHAR_LENGTH(DRUG_GNR_NAME)), MAX(CHAR_LENGTH(DRUG_PRODUCT_NAME)) FROM textfiletable

look at the result and compare the maximum lengths with the column size of the normaltable. For example, if the MAX value for UD_MDC_CODE is 29, then you have to make this column larger. This can be done using this statement which changes the size of the column to 30:

ALTER TABLE normaltable ALTER COLUMN UD_MDC_CODE SET DATA TYPE VARCHAR(30)

Use the ALTER TABLE statement only for columns that have a smaller size than the MAX value. When you have done this for all the columns that are too samll, use your INSERT INTO statement to copy the data from the TEXT table to the CACHED table. The ALTER TABLE statement is documented here:
