Extracting datasets from a csv file

JDzielski — Thu, 08 May 2025 17:40:29 GMT

I have csv file with three datasets included one below another with different number of column each:

header_1_column_1, header_1_column2, ..., header_1_column_n

data1_1_1, data1_1_2, ..., data1_1_n

...

data1_m_1, data1_m_2, ..., data1_m_n

header_2_column_1, header_2_column2, ..., header_2_column_k

data2_1_1, data2_1_2, ..., data2_1_k

...

data2_l_1, data2_l_2, ..., data2_l_k

header_3_column_1, header_3_column2, ..., header_3_column_i

data3_1_1, data3_1_2, ..., data3_1_i

...

data3_j_1, data3_j_2, ..., data3_j_i

My goal is to extract these three data sets to feed three sql tables. I thing about a process:

tFileInputDelimited -> tJava -> tSampleRow -> tmap -> tDBOutput

But I have a problem with determining the row number of the second and third header of datasets and the total number of records from the csv file in the tJava component, to pass these parameters to the tSampleRow component and extract these three datasets. Is it possible to determine the line number in the csv file based on the first occurrence of a given string? - the headers of the three data sets are constant.
